When I first came to Berlin in 1974 I landed at TCA (the official abbreviation of the US Airforce) which at that time still was the main airport of West Berlin. Since 1981 I have been living in Neu-Tempelhof - with the noise of airplanes and the smell of kerosene as an underlying perception of my everyday life. During the last few years I have experienced the comfort of flying from THF (the abbreviation used today internationally) on some occasions – to get to the terminal I could take the number 184 bus from outside my flat and be at the airport within 10 minutes. Then there was the sensation of take-off and landing with the fascinating view of the curved, classical modern façade facing the airfield, and from further away, the overview of the impressive airport building complex embedded in the urban texture of the city of Berlin, a site easily distinguished from the air. To combine these personal experiences and perceptions of Tempelhof Airport, as a resident of Neu-Tempelhof, and as a passenger, with my professional interest in heritage sites was my motivation to choose this topic. Acknowledgements The author is grateful for the support of the following institutions in making documents available: - Untere Denkmalbehörde Tempelhof-Schöneberg - Archiv des Heimatmuseums Tempelhof-Schöneberg My special thanks to those residents who were willing to give me their time and part of their memories related to the airport, as well as lend me photos, postcards, books and magazines from their personal collections. vi 1 Introduction 1.1 Intention of the author The aim of this thesis is to analyse the complex heritage of Tempelhof Central Airport as a whole. The buildings, and their architecture and construction techniques, have already been described and analysed in numerous publications. I will therefore give a summary of the historical context and the main facts only as far as they are relevant for the significance of the site from my broader point of view. The heritage of Tempelhof Central Airport consists of several “dimensions” or “layers” of which the tangible appearance of the buildings is only one. My intention is to identify the different dimensions which are of significance to the airport’s heritage through a more holistic approach to value the site in its own right, and thereby to achieve a better understanding of what defines the heritage of this site, and of heritage in general. The Tempelhof Central Airport building complex was designed by the German architect Ernst Sagebiel in 1935. Construction work started immediately in 1935 but was not finished due to the Second World War. The building opened for civil aviation in 1951, and was listed as a monument in 1994. The building is very well known in Berlin, throughout Germany, and also world-wide because of its history: it forms part of the oldest inner city airport in the world that is still in use, and is still one of the biggest buildings (by volume) worldwide. But “Tempelhofer Feld”, the area where the airport is situated, has a history of its own - related to military use and early aviation - which prepared the ground for the initiation of the first Tempelhof Airport, the predecessor of the current airport complex. For the purpose of this thesis the abbreviation TCA I is used for the first Tempelhof airport from 1923, TCA II for the new airport designed by Sagebiel in 1935. People’s perceptions can be seen as an indicator for the significance and importance of a heritage site. In the case of Tempelhof airport only the perception of the current building (TCA II) will be analysed as TCA I was destroyed in the Second World War. Over the time since the planning of TCA II started, four main 5 perceptions related to the building as such and to its function as airport can be identified: • Tempelhof Central Airport (the building) as example of “state of the art” airport design in the 1930s • Tempelhof Central Airport (the building) as an example for the Nazis’ use of architecture • Tempelhof Central Airport (the building in its function as part of an airport) as a “gateway to freedom” during the Cold War 1946 - 1989 • Tempelhof Central Airport (the building in its function as part of an airport) as a symbol of friendship and support during the Berlin Airlift 1948/49. The perception of a monument or heritage site is connected, inter alia, to the experiences, opinions and personal memories of local people. They own part of the knowledge of the site, a vulnerable knowledge, in danger of being lost if it is not written down or otherwise recorded. To record and analyse this “living memory” of a small number of those residents who have personally witnessed this monument from its construction to its current state (it is probably soon to be closed as an airport) forms an integral part of this thesis. 1.2 Methodology Within this thesis I will use the definition of “cultural heritage” given in the UNESCO World Heritage Convention, as a guideline to identify the heritage of Tempelhof Central Airport. The definitions of the Convention have been drawn up by a long and thorough process, and have currently been accepted by 184 states parties, which is an indicator of their wide general acceptance1. In this context it is not relevant whether or not Tempelhof Central Airport might be considered as of outstanding universal value, but rather, which criteria qualify and characterise cultural heritage according to the Convention. Furthermore, the definition of heritage in the Convention has been reflected in national laws in general, including in the Laws of the Federal States of Germany for the Protection of Historic Properties. The criteria for properties to be listed as monuments are defined, for example according to the Bavarian Law2 for the Protection of Historic Properties (Bayerisches Denkmalschutzgesetz) article 1, 1 http://whc.unesco.org/en/statesparties/, Cited 17/06/2007 The federal structure of Germany means that each Federal State (e.g. Bavaria, Brandenburg, etc) has their own heritage law – Bavaria is a particularly good example. 2 2 paragraph 1 3, a property should have historical, artistic, urban or scientific values. This corresponds with the definition in article 1 of the Convention, given below. Therefore the application of the definition of the World Heritage Convention for a national monument is clearly justified. The Convention differentiates between cultural and natural heritage. For the purpose of this thesis only cultural heritage is relevant. In article 1 of the Convention cultural heritage is defined as “monuments: architectural works […] which are of outstanding universal value from the point of view of history, art or science.” According to article 4 the main aim is the “identification, protection, conservation, presentation and transmission to future generations of the cultural […] heritage” 4. As criteria for the assessment of outstanding universal value, the Operational Guidelines list inter alia “exhibit an important interchange of human values over a span of time or within a cultural area of the world, on developments in architecture or technology […] (paragraph 77, (ii))”; “outstanding example of a type of building, architectural or technological ensemble or landscape which illustrates (a) significant stage(s) in human history (paragraph 77, (iv))”; and “directly or tangibly associated with events or living traditions […] (paragraph 77, (vi))”. In paragraph 78 further conditions authenticity and integrity are mentioned. Authenticity can be expressed by a variety of attributes including: “form and design, materials and substance, use and function, traditions and techniques, location and settings, spirit and feeling” – the later insofar as they can be “important indicators of character and sense of place” (paragraph 83). Information sources, which make it possible to know the nature, specificities, meaning, and history of the cultural heritage, include all physical, written, oral, and figurative sources in paragraph 84 (UNESCO WHC (2005)). Integrity is defined in paragraph 88 as “a measure of the wholeness and intactness of the […] cultural heritage and its attributes”. The proposed methodology for analysing the heritage of Tempelhof Central Airport was: (a) To identify the different heritage-relevant “layers” of the airport. 3 4 http://www.blfd.bayern.de/blfd/index.php?id=1065114, Cited 26/06/2007 http://whc.unesco.org/en/conventiontext/, Cited 16/06/2007 3 (b) To use Tempelhof Central Airport as an example, in order to discuss the problems of preserving and conveying historical events and their values in an authentic way. (c) To identify a number of local Neu-Tempelhof residents who have lived through the different historical phases of the airport and interview them, using a focussed questionnaire, to seek out and record specific information, including: (i) Their first encounter with the Airport, the event this was connected with, the feelings the encounter evoked. (ii) Their present perception of the airport. (iii) If, how and why the perception has changed over time. The results of the interviews will be used to compare the significant aspects of the heritage from the first part of the methodology - section (a) above - with the interviewed residents’ perceptions. (d) To discuss the previously identified aspects of heritage on the basis of the definition of heritage in the World Heritage Convention and the results of Tempelhof Central Airport. (e) To draw conclusions regarding the role Neu-Tempelhof residents play in the intangible aspects of heritage of Tempelhof Central Airport Table 1 gives an overview of how the thesis is structured with references to the chapters where the related topics are covered. 4 Table 1: Overview of the heritage relevant stages of Tempelhof Central Airport (chapters given in brackets) Timeline 18th century Prussia/German Empire (2.1) 1923 Weimar Republic (2.2) 1938 1945 1947-48 Cold War (2.3) Third Reich (2.3) Airlift -1989 1994 Heritage (2.5) Living memory of Neu-Tempelhof residents (5) Tempelhofer Feld (the area) (2.1) as open space Heritage relevant aspects: History of aeronautics/aviation Military history (Prussia and German Empire) Leisure (2.4) Events No events Events TCA I airport buildings with the airfield (occupies part of the area) Heritage relevant aspects: Airport buildings Airfield Function as airport Urban green/sports/allotments TCA II airport buildings with the airfield Heritage relevant aspects: Airport buildings Airfield Function as airport Function as military airport (2.2) (2.3) Remains no remains left some ruins of the buildings and part of the old airfield, small parts building and airfield still in use as airport of sports area and allotments Tangible /intangible aspects intangible Information sources intangible as mostly destroyed tangible for the building intangible for the events history books, photos, paintings, newspapers, movies, recorded memories of contemporary witnesses 5 2 Heritage-relevant “layers” 2.1 Pre-airport times 2.1.1 Early history of the location “Tempelhofer Feld” Tempelhof Central Airport is situated at “Tempelhofer Feld”, an area located about five kilometres south of the centre of the modern city at Brandenburger Tor (Brandenburg Gate). The name “Tempelhof” derives from the ancient “Tempelhove” or “court of the Templar”. The military knights’ order of the Templar founded Tempelhove in 1247 as a “Komturhof” or “commander’s court,” the smallest holding entity of their order5. The airport is situated at the northern boundaries of the former Templars’ estate and today belongs to Tempelhof-Schöneberg, one of the twelve boroughs of Berlin. From the middle of the 18th century the area of Tempelhofer Feld was used for military exercise and public parades first by the Prussian kings and later by the German emperors. The estate was at that time owned by local farmers. The conflicts between the farmers and the military administration about the times of usage and compensation for damage (Bezirksamt Tempelhof 1998, p. 13) ended only in 1826-27 when the Prussian military administration bought the land. In 1873 this area was transferred to the military administration of the German Reich. From the end of the 19th century onwards, Tempelhofer Feld became the stage for another attraction: aeronautics. The age-old dream of flying started to become true with the first successful attempts at ballooning during the 18th century in France. As the techniques and the equipment developed further they also attracted the attention of the military. In 1886 an aeronautic section of the Prussian military was founded. It was stationed in one of the military barracks that had been erected in the western section of “Tempelhofer Feld,” where the soldiers carried out various tests for ballooning (Bezirksamt Tempelhof 1998, p. 16 – 17). 5 http://en.wikipedia.org/wiki/Tempelhof, Cited 02/05/2007 6 Fig. 1: Map of Tempelhofer Feld in 1895 (Conin 1974, pp. 10/11) In 1887 Hermann Wölfert – a publisher and pioneer of aviation – obtained permission and financial support from the Prussian aeronautics military section to carry out some experiments with his construction of a motor driven balloon that could be navigated. On the 12th of June of that year he took off in his balloon from Tempelhofer Feld, but his experiment failed and he and his assistant died in a spectacular crash within sight of the spectators. Fig. 2: Zeppelin (Bezirksamt Tempelhof 1998, p. 25) 7 Another attempt to develop a motor driven airship, started in 1898, was more successful. The famous Zeppelin – named after its inventor and constructor, Graf Zeppelin - was also supported financially by the Prussian aeronautics section. But it took another 11 years before the first Zeppelin landed at Tempelhofer Feld on the 29th August 1909. About 300,000 spectators, including the German Emperor Wilhelm II, watched this memorable event. 2.1.2 Tempelhofer Feld and the start of aviation A different approach to realising the dream of flying was taken by the German engineer Otto Lilienthal 6. He analysed the flight of birds and in 1889 published in Berlin the results of his research in a book with the title: “Der Vogelflug als Grundlage der Fliegekunst” (“Bird flight as the basis of aviation”, English translation in 1911). From 1867 onwards he also experimented with the construction of flying machines to test his findings in practice. Lilienthal died during one of his glider flights in 18967. In the long run his approach of heavier than air flying machines turned out to be more successful than airships, and it was one of the starting points of aviation. The brothers Wilbur and Orville Wright 8 from Dayton, Ohio, United States of America, developed Lilienthal’s ideas further, experimented with mechanical navigation and then started to combine their gliding machines with motors. As part of a promotion campaign for their new motor driven airplane, Orville Wright came to Berlin in 1909 where he wanted to demonstrate flight. This event was sponsored by a local newspaper and took place at Tempelhofer Feld on the 4th of September in front of an audience of about 150,000 spectators. During the following days Orville Wright demonstrated the possibilities of his plane and his aviation skills, and set several new records in altitude and duration of flights. Wright used his popularity to found a firm in Germany for the construction of airplanes, “Flugmaschine Wright GmbH,” financed inter alia by the German industrial giants Borsig, Krupp and AE. At start-up it had orders for 20 planes. 6 Otto Lilienthal, * 23/05/1848 in Anklam, † 10/08/1896 in Berlin, mechanical engineer and “first successful aviator in the history of mankind” (http://www.lilienthal-museum.de/olma /ehome.htm, Cited 27/05/2007) 7 http://www.lilienthal-museum.de/olma/ehome.htm, Cited 27/05/2007 8 Wilbur Wright, * 16/05/1867 in Millville, Indiana USA, † 30/05/1912 in Dayton, Ohio USA, and Orville Wright, * 19/08/1871, † 30/01/1948 in Dayton, Ohio USA, inventors of the motor powered airplane. 8 Fig. 3: Flughafen Tempelhof, Orville Wright’s Aeroplan im Fluge auf dem Tempelhofer Feld. (T3_1636 © Museen Tempelhof-Schöneberg/Archiv) Another event that influenced the further development of aviation in Germany was a national appeal to donate money for this purpose in 1912. It resulted in a sum of 7.5 million Goldmarks9 (national German currency) which was used for training pilots at no charge, for financial support to the aviation industry, and to set up an award system for good aviation performance (Conin 1974, p. 43). The new transportation system had started to develop quickly in Germany, and the military also profited from this development, as it now had access to a number of well-trained pilots. The first purpose-built airfield in Berlin was constructed in Johannisthal in 1908 as Tempelhofer Feld was still owned and used by the military at that time. From 1910 until 1914 Johannisthal was completed and extended and became the centre of aviation in Berlin, where aviation construction firms such as the Wrights’ company were based, where flying schools were opened and new technology was tested at the research institute for aviation. For events like flight competitions or national flight shows the airfield was equipped with stands for spectators. 9 Goldmark, currency of the German Empire from 1871 until 1923; after 1914 the expression Goldmark was used to distinguish it from the paper money of the inflation. 9 After the start of the First World War the military demand for aviation absorbed all available capacity10. The output of the aviation construction industry rapidly multiplied with respect to number of aircraft, number of different types, range and loading capacity (Conin 1974, p. 47). With Germany defeated at the end of the First World War this rapid development came to a standstill in the country. According to the Treaty of Versailles, from 1919 the construction or importation of planes or their parts was forbidden in Germany, and all planes, parts and equipment, including the production sites, were to be demolished (Bezirksamt Tempelhof 1998, p. 33). From 1922 onwards Germany was again allowed to produce planes for civil use, and in 1923 it regained the sovereignty over its airspace, but the production of military aircraft was still prohibited. 11 2.2 The first Tempelhof Airport (TCA I) 2.2.1 The start-up in Weimar times In 1910 the military administration had already sold one part of the area of the Tempelhofer Feld to the municipality of Tempelhof, which at that time did not belong to the city of Berlin but to the town of Teltow. This section - situated to the west of the road to Dresden that was built between 1836 and 1838 – was designed as a Garden City in 1914, but due to the war it was not built until the 1920s. The section to the east of the road to Dresden, the “Berliner Straße,” was still in military possession after 1910. In 1920 the independent villages and towns that surrounded the city of Berlin, including Tempelhof, were integrated into the urban area of “Groß Berlin” (Greater Berlin). With the creation of this new agglomeration, eight towns, 59 rural towns and 27 “rural entities” (Gutsbezirke) with their different regulations, tariffs, transport 10 In WWI the principal use of planes was for reconnaissance and observation. Secondary use was as fighter aircraft armed with machine guns; only a few bombers were built and deployed. (http://www.firstworldwar.com/airwar/summary.htm, Cited 10/06/07) 11 To circumvent this restriction a Junkers factory to produce military prototypes was installed near Moscow (USSR) in 1923 and from 1925 until 1933 the German military in cooperation with the Russian Red Army operated a flying school and testing ground in the town of Lipezk in the Soviet Union. (http://www.bundesarchiv.de/aktuelles/aus_dem_archiv/galerie/00163/index.html, Cited 10/06/07) 10 systems, etc, were unified under one political administration system. This new structure was a precondition for the further urban development of Berlin in order to be able to plan for the whole city on a larger scale and to reserve and distribute areas for the construction of housing, industries and transport infrastructure. Municipality-owned companies provided water, gas, electricity and public transport. The city of Berlin acted as a public entrepreneur itself and also provided the preconditions for the development and success of Berlin’s economy (Rytlewski 2002, p. 10 – 18). The start-up of Tempelhof airport is an example of this approach. For the expanding amount of airmail and freight, as well as the increasing number of flight passengers, quick and easy access to the airport was becoming an important factor. The pre- First World War times of Johannisthal, and the true pioneer days of aviation with flight shows and competitions, where “daredevil pilots” established new records, had gone. The war times with their military use of aviation and the restrictions of the Treaty of Versailles had put an end to this. Aviation had become a business. By the 1920s, aviation as a means of transport had not only been established, but was expanding rapidly and needed a new operating environment with a modern city airport. Business people used the flights, as well as the city council and the government, who for a time met in Weimar. Johannisthal was too far away from the centre of Berlin and was not well connected by public transport. Therefore the main airlines, as well as the German National Mail Company and the Ministry of Transport, were interested in a site with easy access. The man responsible for public transport in the municipalities of Groß Berlin was Dr. Leonhard Adler, 12 in his function as head of the department for transport (“Stadtrat für Verkehrswesen”). He recognised the development potential of aviation, and of Tempelhofer Feld as site for a future inner city airport, and in the end succeeded in convincing the municipality to buy the area from the military for this purpose. 12 Leonhard Maria Adler, * 04/08/ 1882 in Wien, Austria; † 16/12/1965 in Milan, Italy, Austrian–German engineer, politician and after his retirement in 1952 catholic priest (http://de.wikipedia.org/wiki/Leonhard_Adler, Cited 20/04/2007). Chairman of the supervisory board of the Berlin Airport Agency from 1924 until 1933, one of the founders of BVG (Berliner Verkehrsgesellschaft), he went into exile to Italy in 1936 because of the Nazi Regime. From 1948 on he was head of department for transport in Milan (http://www.exilarchiv.de/html/biografien/adler.l.html, Cited 07/07/2007) 11 In October 1923 the two main German Airlines, Junkers and Aero-Lloyd, which in 1926 were to be united to form Lufthansa (still today the German national airline), received a preliminary concession from the Ministry of Transport (Bezirksamt Tempelhof 1998, p. 64) to open a new airport at Tempelhofer Feld. Fig. 4: The first temporary wooden buildings: two Hangars and the terminal building (above), the very first building on the site, from 1923 (left) (Conin 1974, p. 63, 64), The first buildings erected at the northern edge of the area were temporary wooden constructions. One building served for the administration, passenger handling, rooms for staff and the weather station. Two wooden sheds were built as hangars for the planes. During this first year (from October until the end of December) of its existence the new airport had 100 take-offs and landings, where 150 passengers and 1,300 kg of freight (luggage, airmail, newspapers and other freight) were transported (Conin 1974, p. 69). In May 1924 the Municipality of Greater Berlin founded the “Berlin Airport Agency” (Berliner Flughafengesellschaft BFG) with the sum of 500,000 Goldmarks as seed capital (Grosch 1984, p. 276), which in the same year was increased to 1.2 million and in 1925 to 2.0 million Goldmarks by shareholdings from the German Reich. 12 Later, the State of Prussia joined in and increased the capital to 4.0 million Goldmarks, and the shares were divided as followed: 52% held by the municipality of Greater Berlin, 24% by the German Reich and 24% by the free state of Prussia (Conin 1974, p. 72, Rytlewski 2002, p. 18). This financial support demonstrates the importance that the municipality attached to the development of this new traffic and transportation system. Their view was proved to be right, as the traffic figures for these years show. The passenger numbers, for example, increased to more than 20,000 in 1925, over 40,000 in 1927 and reached nearly 54,000 in 1932, the last year of the Weimar republic (for further information see Annex A: Development of passenger numbers, take offs/landings and tonnage of air-freight of Tempelhof airport between 1923 and 1973). Later in the year 1924, the German Government and the Municipality of Greater Berlin drew up a plan (see Fig. 5) for the development of the airport and authorised the newly founded Berlin Airport Agency under the chairman of the supervisory board Dr. Leonhard Adler to carry out the plan. This masterplan shows the integration of the airport into the whole urban context – including integration with the transport infrastructure and the need for public greenspace which Tempelhofer Feld also provided (see table 2). In the German context, this degree of integrated urban planning was quite new. In 1921, empowered by the new administrative structure (described above) the Mayor of Berlin, Gustav Böß, decided to adopt an emergency programme for the employment of people without work. This plan, which had a value of 45 million Reichsmarks, 13 was financed by the municipality of Berlin, the State of Prussia and the German Government. The first programme lasted until 1923, and was then prolonged until 1927 and funded with another 35 million Reichsmarks. The money was mainly spent on the creation of public green spaces and playgrounds, thus preparing for, and already partly anticipating, the “Generalfreiflächenplan” (master plan for the distribution of urban green space for Greater Berlin) of 1929 14 . One of the projects funded by the programme was the “Volkspark Tempelhoferfeld” with a 13 German currency from 1924 until 1948, replaced the Goldmark at a rate of 1 to 1 http://www.stadtentwicklung.berlin.de/umwelt/stadtgruen/geschichte/de/stadtgruen/ 1920_1948/index.shtml, Cited 21/04/2007 14 13 Fig. 5: Masterplan for the Tempelhof airport, published in 1925 (Conin 1974, p. 73, Bezirksamt Tempelhof 1998, p. 38) joint “Sportpark Tempelhoferfeld”, both designed by Erwin Barth 15 . The Volkspark was situated north of hangars 1 to 3 and the Sportpark, east of the airport as a kind of buffer zone separating the nearby tenements of “Oder Straße.” These parks were planned and built between 1921 and 1927. 15 Erwin Barth, * 28/11/1880 in Lübeck, † 10/07/1933, first director of the department for public green spaces and parks (Stadtgartendirektor) of the city of Berlin, designed amongst other Volksparks: Jungfernheide, Rehberge, Mariendorf. He came into conflict with the new Nazi government and commited suicide (http://www.tu-berlin.de/presse/125jahre/festschrift/bart.htm, Cited 21/04/2007). 14 As long as the area was used as military exercise field (see Fig. 1 and map from 1906 in Annex C) it was a large undeveloped open space used by the military and for aeronautics, as well as for leisure and sports activities. It was accessible from three sides and had paths going through. With the transfer of the area from the military to the municipality, this space became a multifunctional area arranged in zones for: • organised sports (stadium for the Preussen footballclub, multipurpose sportsfields of the Sportpark), • organised recreation (allotments and gardens between the airfield and the railway tracks and between “Flughafenstraße”, “Berliner Straße”, “Schwiebusser Straße” and Volkspark), • public urban green space (Volkspark with an open air arena), • airport with buildings and landing area, • the rest was open space (between Flughafenstraße, the railway tracks, airport and Berliner Straße) The new road, Flughafenstraße, interlinked the city districts of Neukölln and NeuTempelhof to the north of the airport, and another road “Grüner Weg”, which probably was a dirt road or path, connected the two districts south of the airport. From the district of Kreuzberg, “Friesenstraße” led to Flughafenstraße. The Volkspark was accessible from all three districts.

First, the area, which was uneven and sandy, had to be levelled. Up to four metres of soil had to be taken off at some points and distributed evenly to achieve a level surface. Soil from the nearby construction site of the new underground railway line was used as landfill, and later when all this material proved to be not enough, waste from urban rubbish collection was used as filler material. A topping of suitable soil, with tons of grass seeds and fertiliser, was put over this to finish the task of producing an even grassy surface for the landing strip. A flock of sheep was brought in as “lawn mowers” and to produce natural fertiliser. The implementation of the airport development plan had started with the construction of permanent buildings at the end of 1924, to replace the temporary wooden ones. This was carried out in two phases. Section one included: hangars 1, 2, and 3 (dimensions 64 by 25 metres, each with two doors of 30 by 6 metres), offices, workshops and laboratories, which were all designed by architects Paul Mahlberg and Heinrich Kosina, and a radio station which was designed by Fritz Bräuning, the architect of the garden city of Neu-Tempelhof. Phase two comprised: hangars 4 and 5, also designed by Mahlberg and Kosina, which had bigger dimensions (80 by 30 metres, each with two doors of 40 by 8 metres) than the earlier hangars due to the growing demand for space. The hangars were equipped with a patented system of motor driven foldable sliding doors used for the first time (Bezirksamt Tempelhof 1998, p. 46). The airfield comprised of an omni-directional grass field with a diameter of about 1,000 metres – which was usual at that time – with a concrete apron in front of the hangars and terminal building of about 100,000 square metres, and a concrete taxiway in a semi circle around the grass field (Bezirksamt Tempelhof 1998, p. 43). To assist identification from the air the name Berlin in big white letters was inserted in the concrete (see Fig. 6). The airfield was illuminated to permit night flights. A competition was held in 1925 for the design of the main administration building including the departure hall, passenger lounge and other facilities (such as a restaurant, hotel, and a ball room). The design of the winning architects, Paul and Klaus Engler, had to be modified to bring it in line with the traffic access concept of the development plan of the airport (Bezirksamt Tempelhof 1998, p. 43). The construction work was to be carried out in three sections without stopping the ongoing operation of the airport. The first section started in July 1926 and comprised of a core building in the centre, the 17 second section followed in 1928 enlarging the core building at three sides. They were both handed over in 1929. The third section was to extend the building at both ends. This was the first known airport terminal which included design for future expansion (Voigt 2005, p. 15). Fig. 6: Airport building June 1930 (private collection Stefan Lehmann) In 1926 – as part of the development plan for the airport - construction was started of a new east-west road, Flughafenstraße, in order to improve access to the airport. It connected the airport with the big north-south avenue Berliner Straße (today “Tempelhofer Damm”) on the west and “Hermannstraße” in Neukölln on the east. Also in the same year the new underground station “Flughafen” (today “Paradestraße”) of the extended underground railway line C “Nordsüdbahn” was opened (BohleHeintzenberg 1980, pp. 161). The new station, designed by the architect Alfred Grenander16, was situated where Flughafenstaße joined Berliner Straße. The main entrance hall of this underground station was in line with Flughafenstraße and spacious enough to hold the large numbers of spectators arriving and departing from the flight shows. A foot passenger tunnel was planned to connect the station directly to the airport building but was not built. 16 Alfred Frederik Elias Grenander (* 26/06/1863 in Skövde, Sweden; † 14/07/1931 in Berlin) Swedish architect, who designed the majority of the Berlin underground and elevated railway stations. 18 Fig. 7: Airport underground railway station (Bohle-Heintzenberg 1980, p. 172) Fig. 8: Aerial photo viewing east from about 1932, Neu-Tempelhof in the foreground, Flughafenstraße and airport buildings in the background (T3_1586 © Museen Tempelhof-Schöneberg/Archiv) 19 Other public transport routes which could be used to get to the airport were tramline 99 which already existed, and ran along Berliner Straße 17 , and a new tramline running from Berliner Straße along Flughafenstraße with its final stop in front of the airport 18 . Lufthansa, the newly founded German national airline, also set up a free shuttle bus service between Berlin city centre and Tempelhof Airport (Conin 1974, p. 101). The approach to the layout of TCA I indicates the importance the municipality placed on this project and is an example of the efficiency of the new administrative structures. A masterplan provided for the necessary infrastructure and the location of the airfield and the buildings within the urban context. This was very different from the way the early airfields like Johannisthal were arranged – with a cluster of buildings somehow at the edge of the landing area. The Tempelhof buildings were aligned along the new access road Flughafenstraße. The technical buildings like hangars and radio station were erected first. The competition held for the terminal building shows the growing importance of passengers and visitors – a building with representative but as well functional architecture was required. Voigt commented about the airport in the 1920s: “The terminal was now beginning to evolve as a distinctive architectural ensemble, in the history of European airports. The buildings, almost always placed at the field’s periphery, are not simply lined up, but rather arranged to a recognisable plan.” (Voigt 2005, p. 14) When the terminal building was opened in 1929 it comprised only one seventh of the planned final size (Dittrich 2002, p. 17). However, it had already become obvious that the planning of the airport complex could not keep pace with the actual development of aviation at Tempelhof airport. The layout of the whole airport – the functional concept as it had been planned in 1926 - would not be able to cope with the rapidly growing volume of air traffic. From 1926 to 1929 the number of passengers increased by about 30%, and the weight of freight more than doubled (see Annex A, table: Development of air traffic in Berlin). In the 1930s TCA I 17 http://www.berliner-verkehr.de/trbilder/netz_bsg_1923.jpg, Cited 09/04/2007 18 http://www.berliner-verkehr.de/trbilder/netz_bvg_1930_west.jpg, Cited 09/04/2007 20 became the leading European airport in terms of the volume of air traffic (Bezirksamt Tempelhof 1998, p. 44). Another problem for the development of Tempelhof airport was the shortage of money caused by the world economic crisis from 1929 onwards, which affected investments in the public sector. As a result, further construction work after the second phase of the new terminal building was not carried out. 2.3 The new Tempelhof Airport (TCA II) 2.3.1 The building process in the Third Reich 2.3.1.1 The initiation The Nazi government came into power in Germany in January 1933. Adolf Hitler, the Chancellor of the new government, had already developed plans for the design of the future capital of Germany, “Germania,” which he presented to the municipality of Berlin in September 1933 (Dittrich 2002, p. 19). The main idea of his concept was the creation of a huge north-south axis in addition to the already existing east-west axis of “Unter den Linden” and “Charlottenburger Chaussee”. The new north-south axis started in the south with a large new railway station from where a wide boulevard ran north, culminating in a giant hall with a dome. Tempelhof Airport as a site was connected to this boulevard. The Berlin Airport Agency responded to this master plan by instructing the architect of the hangars of TCA I, Heinrich Kosina, to start work on the design of new airport buildings which would meet the future aviation requirements of the capital. These were to be located on the north-west edge of the existing site, close to Berliner Straße, with a connection to the boulevard of Hitler’s Germania concept. Kosina’s plans were presented to Hitler in 1934. Hitler wanted the project to be started quickly, and he formulated the demand that it should be the largest and most beautiful airport of the world and announced financial support from the state for the project. The “Reichsluftfahrtministerium” (Ministry of Aviation), as representative of the government, was already part of the supervisory board of Berlin Airport Agency, and was informed about the plans. When the Agency had problems in 1935 with the 21 Fig. 9: Model of the north-south axis (Dittrich 2005a, p. 7). Curved edge of Tempelhof airport building visible on extreme right of photograph. financing for such a big project, which were likely to delay the start, Hitler promised to provide the initial 5 million Reichsmarks necessary to start the work from the budget of the Ministry of Aviation. 22 This was a turning point for the project. Berlin Airport Agency and the municipality, as main shareholders, were no longer able to act independently. The Ministry of Aviation took over responsibility for the project from the Berlin Airport Agency and transferred the planning of the new Tempelhof airport to its own architect Ernst Sagebiel19. Sagebiel had started to work for the ministry in 1933, and since 1934 he had been head of the building department for special tasks (Dittrich 2005a, p. 32). Apart from other smaller projects like barracks and schools for air force pilots, he had designed and carried out the construction of the Ministry of Aviation building (Wilhelmstr. 97, today the headquarters of the Ministry of Finance). Sagebiel and the staff of his department (about 150 architects, engineers and office staff, Dittrich 2005b, p. 164) took over work on the design and were able to present the plans for the first time to Hitler in November 1935. In March 1936 Hitler gave his approval to the final version. At that time preparatory earthworks along Berliner Straße had already started. Sagebiel’s final design was influenced by Albert Speer in small details (Dittrich 2005a, p. 16) as the plans were already advanced when Speer came into power as “Generalbauinspektor” (General inspector of construction) of the Third Reich at the beginning of 1937. 2.3.1.2 Description of the new airport building complex The main characteristics of the new building complex were the following: Integration into the urban context The plans showed a strictly symmetrical design along a main axis leading southeast to north-west, aligned with Schinkel’s cast-iron landmark on the “Kreuzberg” hill (erected in 1821 in remembrance of the liberation wars). A big circle (250 metres in diameter, Conin 1974, p. 185) marked the area where the wide boulevard of Berliner Straße met “Belle Alliance Straße” and “Immelmannstraße” (today “Dudenstraße”). The road to Neukölln (“Columbiadamm” the continuation of Immelmannstraße) did not yet exist. Through Immelmannstraße the future airport was to be linked to the North-south axis of Hitler’s new capital, Germania. From the landmark on the Kreuzberg hill a large promenade with a water basin was to lead in big step-like sections down to the circle, where the start of a basin was 19 Ernst Sagebiel, (* 02/10/1892 in Braunschweig, † 05/03/1970 in Starnberg), architect, from 1933 on working for the Nazi government’s ministry of aviation, main buildings: headquarters of the Ministry of Aviation, Tempelhof Central Airport, Airport München-Riem 23 marked with two obelisks. This part made up about one quarter of the planned circle. This is clearly shown in the photograph of the drawing, figure 10, below. Fig. 10: Perspective of the planned airport building (Dittrich 2005a, backpage) The other three quarters of the circular building complex were aligned with buildings designed in the same uniform style, of the same height and with the same façades. In the quarter opposite the water basin the buildings opened up to give way for the big square (90 by 80 metres, Conin 1974, p. 185) bordered on the long sides with lower buildings with colonnades. On the narrower side - as a counterbalance to the procession-like way up to the landmark - the main terminal building closes the square. This building is two storeys higher than the others and has a differently arranged façade, underlining its importance. On the top of the building a huge iron eagle (4 metres high), designed by Sagebiel, marked the centre of the building complex emphasising its symmetrical character. The terminal building is accessible through the entrance hall (measurements: 80 by 10 m, height 15 m) which opens to the departure hall situated five metres lower (measurements: 50 by 100 m, height 19 m). The front wall of the departure hall was to be glazed to enable passengers and visitors to view the airfield. To the right and left of the departure hall, adjacent parts of the building complex are arranged around separate courtyards, for freight and postal services. Through the departure hall passengers can reach the departure gates from where stairs lead down to the boarding area (see Figures 12 and 13). This 380-metre-long boarding area forms the middle part of an arched lintel with a total length of about 1230 metres. The hangars are connected to the right and to the left of the departure gate and follow the bow shape. 24 Legend: 1 Building complex TCA II 2 Apron 3 Parking place for anchoring 4 Taxiway 5 Start stumps 6 Road 7 Grass strip for spectators 8 Railway tracks 9 Works yard 10 TCA I Fig. 11: Masterplan of the airport TCA II 1936 (Bezirksamt Tempelhof 1998, p. 81) The design of the airfield was a compromise between the grass fields of the first generation of commercial airports like TCA I, and concrete runways which had been developed in different patterns to meet the requirements of the increasing air traffic and bigger and heavier airplanes. Hard runways were already in use in other European countries and the United States (Voigt 2005, p. 17). Tempelhof airfield was oval shaped and still used a grass surface, but was surrounded by a concrete taxiway which had three semicircular ‘start stumps’ where aircraft waited for take off (see Fig. 11, and aerial photo in Annex D, where two of the start stumps can still be seen). 25 Fig. 12: Structural cross-section of the boarding area (Hecker 2000, p. 96) Cantilever construction of the 40-metre overhang of the canopy by A. Schleusner Fig. 13: Boarding area (Hecker 2000, p. 97) 26 The functional concept The concept is characterised by vertical separation of visitor- and passenger flows and transportation systems, an idea which had first been carried out at Hamburg’s Fuhlsbüttel airport in 1929 (Voigt 2005, p. 15). Visitors have access to the balustrades of the departure hall via staircases from where they can watch the proceedings in the hall. Passengers stay on the level of the departure hall and departure gates from where they go down the stairs to the covered boarding area. “For the first time, an airport terminal aligns numerous gates – twenty in all – corresponding with parking spaces for several waiting aircraft and enabling large numbers of passengers to embark or disembark simultaneously.” (Voigt 2005, p.20) Baggage handling takes place in the level directly below the departure hall. This level is connected with the postal and the freight areas through a ramp and from there as well with the railway tunnel which is situated one level deeper, at the same level as the courtyards of the freight and postal areas. The railway tracks run along the town side of the arched lintel (at the lower level of the courtyards) and cross underneath the terminal building in a tunnel. The two courtyards for freight and postal services also have access to Berliner Straße (now Tempelhofer Damm) and Columbiadamm. With this system of vertical separation, road traffic, railway and air traffic are interlinked with freight and mail. Impact on the urban surroundings of the airport To accommodate the design for the new Tempelhof airport, the whole area south of Schwiebusser Straße which had been used for pleasure grounds, sports fields and small gardens and allotments, as well as for the public park (Volkspark), was cleared. Columbia House, which was located opposite the police barracks – a former military prison which served as one of the first concentration camps in Berlin from 1933 onwards – was also demolished in March 1938. The small gardens and allotments north of the railway (Ringbahn) up to Grüner Weg were mostly cleared. The model below in Fig. 13 gives an impression of how much space was cleared to give way to the airfield of the new airport. 27 Fig: 14: Wire model of the new airport on top of the first airport (Dittrich 2005a, p. 6) With the new airport, TCA II, the area underwent a second transformation: originally multipurpose the area had changed to zoned and now became a single function space which was nearly completely occupied by the airport buildings, landing area and outfield (see Table 1). Only one small area of allotments was left close to Tempelhof station at Berliner Straße. All the former roads and paths were closed and removed. 28 Key points regarding the concept and building process Ernst Sagebiel, as head of the planning department of the ministry of aviation was equipped with (a) the financial means, (b) sufficient staff to finish the planning in an impressively short time, (c) authorisation from Hitler and the ministry so that there was no interference or delay caused by the planning authorities of the municipality and (d) until the beginning of the Second World War, with a large enough labour force to carry out the construction. Provided with all these favourable circumstances he designed a building complex that still impresses today with its architecture, including its setting in the urban context, proportions, use of different styles and materials, functional concept and construction techniques. The architect fulfilled the Nazi government’s requirements to build the largest building in the world (if the goal of the absolute largest was not met the Airport building was certainly amongst the largest). He used appropriate architectural methods and styles, available at that time, to create a most impressive building. Furthermore, he met the objective of providing a building complex which should not only serve as an airport but also as an air stadium for the masses and a place of mass recreation and entertainment. The functional concept was at the leading edge of airport planning in Europe, if not in the entire world, the construction techniques were partly developed for the project and used for the first time in this building, the whole construction system was described at length and published in the leading German architectural and construction engineering professional journals. It can be said that the functional concept and the construction techniques were truly groundbreaking in the 1930s. 29 2.3.1.3 The building process, and use until the end of the war “The rapid construction of the ensemble demonstrates the mastery of civil engineers of the second half of the 1930s in the realm of high quality reinforced concrete buildings. Work started on the terminal in 1935 and by December 1937 the basic structure had already been completed. Construction slowed down considerably, however, following the outbreak of the Second World War in the autumn of 1939. Hitler lost interest in the airport’s role as a manifestation of the international prestige of his regime.” (Hecker 2005, p. 93) In the middle of 1938 Lufthansa moved into the already completed building sections Columbiadamm/Platz der Luftbrücke (aisle buildings east of the courtyard). Berlin Airport Agency followed in 1939 (aisle buildings west of the courtyard) (Dittrich 2005b, p. 173). Due to rationing of building materials and a lack of labour force the construction process slowed down and the building could not be completed according to plan in 1939. After the beginning of the war in September 1939 the building sections that had been completed were used for military purposes. The construction work on those building sections that were meant for military use, were carried on, the work for the civil airport came to a standstill in 1942. From 1940 onwards the buildings of TCA I and TCA II were used by Weser Flugzeugbau GmbH20. As their main production site in Lemwerder near Bremen was too exposed to allied bombing, the “Reichsluftfahrtministerium” (RLM) decided to relocate a part of the production facilities to Tempelhof airport. This included retrofitting of civil aircraft for military purposes and the assembly of new warplanes, mainly Ju 87 and Fw 190. In total, 1,960 Ju 87 aircraft were assembled and checked at Tempelhof airport between 1941 and 1944 when production of this model ceased (Wenz 2000, p. 120) in favour of the Fw 190. The parts for aircraft manufacture were delivered by train to TCA II. The production occupied five of the seven hangars and the departure area of TCA II (51,673 square metres) and most of two of the five hangars of TCA I (10,090 square 20 Weser Flugzeugbau GmbH, aircraft production company founded in 1934 as limited company in Bremen, the fourth biggest producer of aircraft in Germany during the Second World War (http://de.wikipedia.org/wiki/Weser-Flugzeugbau_GmbH, 18.06.2007). 30 metres) (Wenz 2000, p. 114). In 1944 – at the peak of employment - 4,151 persons worked for Weser Flugzeugbau GmbH at Tempelhof airport, of whom more than 50% were foreign forced labourers – either prisoners of war, mostly from France, Poland or Russia, or civilians from occupied countries like Belgium, the Netherlands, and Czechoslovakia (Wenz 2000, p. 134-135). For the forced labourers of the eastern countries a camp of barracks had been erected on site close to hangar 1 at Columbiadamm. For the forced labourers of the western countries accommodation had been rented in the district of Berlin-Schmargendorf (about 6 km west of the airport). For about 500 employees/staff of Weser Flugzeugwerke GmbH who had moved to Berlin, flats had been provided in blocks which had already been emptied to be demolished for the new airport buildings west of Berliner Straße (Wenz 2000, p. 115). Fig. 15: Production of war planes Ju 87 in hangar 4 (Wenz 2000, p. 58). The old airport buildings (TCA I) - with an interlude of September 1939 until March 1940 (Bezirksamt Tempelhof 1998, p. 86), when the airport was transferred to Rangsdorf south of Berlin due to the beginning of the war – served as Berlin’s airport until April 1945. Between 1929 - when the new main departure hall had been opened - and 1938 (the peak of air traffic at TCA I) the passenger numbers had multiplied by six (see table in Annex A). The buildings of the first Tempelhof Central 31 Airport suffered from heavy bombing during the war and were nearly completely destroyed. Sagebiel’s new airport building complex was not completed according to the original design of the architect partly due to shortages caused by the war and also due to a change in the urban development concept; Speer had now planned three to four new airports at the outskirts of Berlin (Dittrich 2005b, p. 174). The buildings west of Tempelhofer Damm (former Berliner Straße) and the connection to the Schinkel monument were not constructed. The principal axis therefore cannot be identified in practice today. The big iron eagle crowning the top of the entrance building and marking the centre was taken down in the 1960s to make way for the antenna of a radar system. The trees growing in front of the wing buildings along the square of “Platz der Luftbrücke” as well as the vegetation growing in the square itself further lessen the symmetrical image. Therefore the design and the arrangement of the whole complex can today be perceived in the intended grand-scale monumental way only with difficulty. 2.3.2 TCA II in its function as airport 2.3.2.1 After World War II – the beginnings of the Cold War 21 21 The term “Cold War” was introduced in 1947 by two Americans: Bernard Baruch a financier and presidential advisor, and Walter Lippmann a writer, journalist and political commentator. It describes “the period of conflict, tension and competition between the United States and the Soviet Union and their allies from the mid-1940s to the early 1990s. Throughout the period, the rivalry between the two superpowers was played out in multiple arenas: military coalitions; ideology, psychology, and espionage; military, industrial, and technological developments, including the space race; costly defense spending; a massive conventional and nuclear arms race; and many proxy wars. ” (hppt://en.wikipedia.org/wiki/Cold_War, Cited 21.04.07) The only place where representatives of the two powers had direct contact was the divided city of Berlin. The Truman Library (part of the national archives of the USA) gives the following explanation for the start of the Cold War: “Historians have argued long about when the "Cold War" between the United States and the Soviet Union began. Some cite Churchill's "Iron Curtain" speech at Fulton, Missouri in March 1946. Others cite the decision by the United States to offer "mutual assistance" to Greece and Turkey in 1947 to combat Communist guerrilla forces, while others would state it was the recognition by US policy officials that Communist stated goals had not changed since 1918, only their tactics. Regardless of exactly when the "Cold War" began, in about 1947 the US policy with regards to the Soviet Union changed from cooperation or, at least, attempting to get along with Soviet Communism, to a policy of "containment." (http://www.trumanlibrary.org/whistlestop/BERLIN_A/BOC.HTM, Cited 04/07/2007) 32 After their victory in 1945, the Allies had divided Germany into four military occupation zones – France in the southwest, Britain in the northwest, United States in the south, and the Soviet Union in the east. The former capital Berlin, which was situated in the Soviet zone, had a special status. It was divided into four military occupation zones as well. The occupied zones were controlled by the Allied Control Council based in Berlin Schöneberg which was responsible for the central administration of Germany, and for guaranteeing that this administration was carried out in a uniform way in all the zones. The state of the airport The capitulation of Berlin was signed on the 2nd of May 1945 in Neu-Tempelhof, Schulenburgring 2. Russian soldiers had taken the airport in the last days of April but later had to hand it over to the US Air Force on the 4th of July as the area belonged to the American Sector according to the Yalta Conference which had been held in February of the same year. The buildings of the old airport TCA I were almost completely destroyed during the war. The new buildings - though being clearly visible from the air - suffered little damage. This has been attributed to their solid construction (as mentioned in Wenz, 2000, p. 130, Conin, 1974, p. 205), but might also be due to be the allies’ intention to use these buildings in the future for their own purposes. Fig. 16: Damaged departure hall of TCA II (Conin 1974, p. 217) 33 Nevertheless some of the large steel beams of the main construction of the departure area and the hangars were deformed by fire and had to be replaced. The departure hall had partly collapsed. (See footnote below for further historical detail about the airport director and the terminal building22). Several parts of the building had suffered damage from local fires. It is not clear who caused the fires – some happened after the Red Army had taken the airport. The well-secured bunkers were set on fire by the Red Army when they tried to enter them and in doing so forced the steel doors open with explosives. The contents of these secret chambers is unclear, it seems that they contained paper documents and film material. The contents burnt for several days due to the good ventilation system of the bunkers. The start of TCA II as a military and civil airport The new airport buildings which had been designed and constructed under the Nazi Government to demonstrate Germany’s superiority, but had not yet been used as an airport, were put into operation by the United States Air Force (USAF). The USAF confiscated the whole area of the airport and started immediately to clear up what had been left by Weser Werke and the Russian Army. This unfortunately included 22 The mystery about the last director’s death Rudolph Böttger had been director of the Berlin Airport Agency since 1926. He died in the last days before the airport was conquered by the Russian Red Army. The circumstances of his death are unclear. Some sources say Rudolf Böttger had been given the order by the Nazi government to destroy the airport to prevent it from falling into the hands of the enemy. There exist several versions of the circumstances of his death. The most frequently published version is that he committed suicide because he did not want to destroy the building (Conin 1974, p. 207, Bezirksamt Tempelhof 1998, p. 86). Another source cites the report of a contemporary witness from July 1945 (an employee of Weser Werke, which produced war planes in the new airport building, who stayed at the airport until the 24th of April) who says that Böttger had tried to be neutral and had forbidden staff to defend the airport. The witness then heard from SS members at the airport that they had shot Böttger and his assistant as the two men tried to take away important secret documents (Wenz 2000, p. 144). A third version is described at the website of ICAT (Interessengemeinschaft City-Airport Tempelhof e.V, an association for the preservation of Tempelhof Airport) which goes back to the first director and initiator of Tempelhof Airport, Dr. Leonhard Adler, whose son reported the circumstances as he had heard them from his father. Böttger had only tried to detonate the ceiling of the departure hall but not the whole building and therefore had been shot by an SS officer. The third version would explain why the floor of the departure hall had collapsed into the storey below (see Fig. 17). (http://www.flughafen-berlintempelhof.de/Leonhard_Adler.html, 10/04/2007) 34 most of the documents and records concerning the construction of the new airport buildings (Conin 1974, p. 209, Bezirksamt Tempelhof 1998, p. 137). The US Air Force started to repair the damage with a requisitioned civilian German labour force, and finished those parts of the buildings they needed to operate the airport. The Municipality of Berlin named a former member of the airport administration as German counterpart for these operations, due to his experience. From the 1st September 1945, Tempelhof Airport was operated as a military airport (Freundt 2001, p. 10). From the 18th May 1946 (Bezirksamt Tempelhof 1998, p. 90) the American Overseas Airlines (AOA) started the civil air traffic with a weekly flight to Frankfurt am Main. Until the end of the war Tempelhof airport had grass runways which were no longer considered as “state of the art”. The US Air Force built a provisional running strip with pierced steel planking (PSP)23 placed on top of the grass field to enable their heavier planes to land. 2.3.2.2 The Berlin Airlift and its impacts on TCA II From the beginning of 1947 the political situation in Germany, and especially Berlin, started to become more and more difficult. The Four Powers, with the three western allies on one side and the Soviet Union on the other side, had diametrically opposed opinions about the future development of Germany and Europe. As they were not able to reach any agreement, the US and the British created a so called “bizone” merging their occupation zones as part of preparations for currency reform, the first step towards installing an independent West German State. The Soviets understood this as a violation of the Potsdam Agreement of 2nd August 1945 where the tasks of the Allied Control Council had been put into writing, and left the Council in protest on the 20th of March 1948, which from then on ceased to function. After the French, who had hesitated to join the currency reform, finally agreed to do so on June 17, 1948, the currency conversion in the Western Zones of Germany was officially announced on June18, by the Military Governors of the US, British and 23 Pierced Steel Plank (PSP) is a military solution for rapidly providing temporary roadways and runways using interlocking steel sheets which are “pierced“ with large, flanged, holes to reduce weight and increase stiffness. 35 French Zones 24 . On June 24, the day when the new West German currency, the D- Mark, was distributed in West Berlin, the Soviets blocked all land and water based access to the three western sectors of Berlin and stopped electricity supplies. This blockade lasted until May 11, 1949. For air traffic to Berlin, the Four Powers had already agreed on three air corridors in November 1945, and had set up the Berlin Air Safety Centre in February 1946. This was situated in the Allied Control Council building and functioned until the fall of the Berlin wall in 1989. On June 25 1948, the commander of the American occupation zone in Germany, General Lucius D. Clay, in agreement with the British and French Allies, gave orders to start an airlift with military and civil aircraft. The operation started on June 26, 1948 and lasted until September 30, 1949. The Berlin Airlift was carried out by the US Air Force under the name “Operation Vittles”, by the British Royal Air Force under the name “Operation Plainfare” and by British civilian aircraft on contract. The aim was to sustain the 2.1 million inhabitants of West Berlin and their own staff. The total delivery to Berlin added up to 2,325,510 tons of cargo of which US Air Force contributed 76.7%, Royal Air Force 17% and British civilians 6,3%. The total number of flights amounted to 277,569 (Miller 1998, p. 108 – 109). To support the economy, goods produced in West Berlin (in total 21,000 tons) left the city with outgoing aircraft – stamped “Made in Blockaded Berlin” (Bezirksamt Tempelhof 1998, p. 108). The whole operation of the airlift was a masterpiece of logistics and operational skills. To provide the population of West Berlin with only the basic subsistence for one day a minimum of 2,000 tons had to be delivered. The US Air Force’s largest available transport plane was the Douglas DC-54 Skymaster (loading capacity 10 tons) but in Europe they had only the much smaller DC-47 (loading capacity 3 tons). One of the first tasks therefore was to organise the transfer of DC-54 planes from the United States which completely replaced the DC-47 from October 1948 on (Freundt 2001, p. 13). The planes used the northern and southern air corridor (see Fig. 18) for the incoming flights and the middle corridor for the outgoing flights. 24 http://www.trumanlibrary.org/whistlestop/BERLIN_A/PAGE_3.HTM, 04/07/2007 36 Fig. 17: Berlin Air corridors (Jackson 1988, p. 8) At the beginning of the airlift only two airports with one runway each were available, Gatow in the British sector at the western edge of West Berlin and Tempelhof. In response to the emergency - as a combined action of the US Air Force and the Berlin population - a new airport was constructed within three months, at a former German military training area in the French sector, and put into operation on 37 November 5, 1948. The river Havel and the Wannsee served as landing places for seaplanes. Among other supplies they brought bulk salt (Jackson 1988, p. 55) for the chemical industry in Berlin, as they were made of “Dural” which was not affected by the salt, unlike the aluminium of other planes. The availability of Tempelhof airport with its large partly-roofed apron for unloading, and the infrastructure of buildings and transport links to the city to store and distribute goods, as well as its central location, enabled a very rapid start to the airlift – and crucial support for the continued high volumes for over a year. The allies’ ability to start bringing in and distributing large quantities of supplies within a few days of the start of the blockade was only possible because of the availability of TCA. From August 1948 on General William Tunner was in charge of the “Operation Vittles”. He set up new flying rules with standardised processes to increase efficiency and safety. Planes took off every three minutes day and night, constantly keeping at this interval, speed and height throughout the whole flight (see Fig. 18). Fig. 18: Cross-sectional view of airlift flight scheme September 1948 (http://www.centuryof-flight.freeola.com/Aviation%20history/jet%20age/The%20Berlin%20Airlift.htm, Cited 29/06/2007) On arrival, pilots had just one attempt to land and if that failed for whatever reason they had to fly back with their load so as not to hinder the next planes in the queue. On the ground the flying crew stayed on board, was provided with food and the weather forecast for the flight back, while German workers unloaded the planes and a team of mechanics did field maintenance (Miller 1998, p. 74); then they took off again. At their arrival back in West Germany the ground crews had one hour and 40 minutes time to refuel, reload and prepare the plane – including maintenance - for the next flight into Berlin. 38 For Tempelhof Central Airport the Airlift was an endurance test. As the largest of the allied airports, and also the one with the best connections to the city, including the railway, Tempelhof airport was the most important landing port for the incoming goods. Of the total sum of about 2.3 million tons of freight 1.7 million tons came in through Tempelhof. Of this, 67% was coal, 24% food and 9% medication, newspapers and raw materials 25 . Most of the coal was for the power plants to produce electricity, only a small amount was used for heating. Tempelhof airport’s one runway was not strong enough for the heavy planes and not durable enough for the large number of landings and take offs. Therefore from July 1948 until the end of November (Miller 1998, p. 59 – 60) two more runways north and south, parallel to the first one, were built, this time on a more solid base of rubble from bombed buildings. But the PSP still broke and had to be repaired inbetween the take offs and landings. Gradually, it was improved by adding an asphalt layer on top (Conin 1974, p. 221). Apart from the rubble, all other materials had to be flown in. A German labour force under guidance of US engineers carried out the work in daily shifts between 7 am and 11 pm. The organisation of the unloading and further distribution of the goods was the next challenge. Employment centres provided the necessary people which was not such a problem – a lot of people were unemployed and happy to work for a daily wage of 1.31 Marks (about the same as an industrial worker). Another welcome privilege was to get a meal at the airport canteen for 50 Pfennig (0.50 Mark). Apart from the civilian workers, former soldiers who had been American and British prisoners of war were required, amongst others, because of their language skills (Bezirksamt Tempelhof 1998, p. 93). From the planes the goods were unloaded onto military trucks (see Fig. 20), transported to a ramp at the edge of the airport area near Tempelhofer Damm and then reloaded onto private trucks for further distribution. The district of Tempelhof with its harbour at “Teltow Kanal” (situated about 4 km south of the airport following Tempelhofer Damm), its many industrial buildings and railway tracks connecting the airport to the railway system of Berlin provided favourable conditions for the distribution. The big storehouses at the harbour were the first destination for storage 25 (http://semmer.de/airlift/, Cited 19/04/2007) 39 and further distribution but as the amount of goods grew larger other industrial storehouses in the surroundings were used as well. Fig. 19: Summer 1948, airlift planes at TCA II in a queue to be unloaded (Bezirksamt Tempelhof 1998, p. 92) For the unloading of coal onto railway wagons another ramp was built and from August, 30 1948 on a shuttle service of 22 wagons drawn by a steam engine (Bezirksamt Tempelhof 1998, p. 98 – 99) transported the coal to the Teltow Kanal for further transport by steam boats to the power plants. Coal turned out to be a tricky item to handle. In the beginning coal was transported in coffee sacks which were not suitable for this purpose. They wore out quickly and let the coal dust through which damaged cables and electrical connections and caused breathing problems for the flight crews. The use of army duffel bags somewhat improved this situation but was too expensive. The problem was solved with the introduction of single-use multi-layer paper sacks manufactured specifically for the airlift (Miller 1998, p. 86). In the course of the airlift the daily capacity of flights and freight increased due to improvements in the organisation, loading techniques and equipment. At Tempelhof airport, the monthly delivered tonnage increased from 36,000 in July 1948 to 90,000 in April 1949 with a peak of 1,000 landings and take-offs a day in that month (Bezirksamt Tempelhof 1998, p. 105). This figure was never again achieved. 40 Less well known than the import of supplies to Berlin in the airlift, is that “Displaced Persons” were transported from Berlin to Frankfurt in the empty airlift planes. In one week, between the 23rd of July and the 1st of August 1948, 5536 persons from the two Displaced Persons camps in the American Sector (Königseder 2002, pp. 40, Bezirksamt Tempelhof 1998, p. 95) left Berlin via Tempelhof Central Airport. They were principally Jewish people who had taken refuge in Berlin because of antiSemitic excesses after the end of the war in the Soviet Union and Poland. They were only a small part of the approximately 32,000 Jewish refugees from the eastern countries who passed through Berlin from autumn 1945 onwards, in search for a new country to live in. Soon afterwards the two camps were closed down. For the Berlin population the blockade was a real threat and the quick reaction of the western allies, led by the USA, was warmly welcomed and started to transform their relationship with the German people from occupying, to protecting, powers. The experience of the blockade also had some impacts on the behaviour of the population of West Berlin 26 as well as on politics of the Federal Republic of Germany concerning precautionary measures 2.3.2.3 27 . The further development of TCA II during the Cold War Return to partly civil use After the end of the airlift, which had provided TCA II with two new hard surface permanent runways, the everyday life of the military airport returned to normal. Even throughout the airlift the passenger service of the civil airline AOA had continued operations and had transported approximately 30,000 people (Treibel 1992, p. 67). 26 As a side effect of the blockade the Berlin population started to developed a so called “Inselmentalität” (insular mentality) the feeling of living on an island surrounded by an enemy which was enhanced by the construction of the Berlin Wall. As a consequence some residents of West Berlin who could afford it, bought property in West Germany close to the German/German border and on Friday afternoons left Berlin to spend the weekend at their properties in West Germany. 27 Another more practical result of the blockade was the storage of staple foods and other goods (so called “Senatsreserve”) and the production of local gas to make the city independent of external energy supply. In order to be prepared for a future blockade, the local government of Berlin put into storage enough supplies of food, medication, fuel, coal and raw materials for local industry to guarantee the survival of the Berlin population for six months. These goods (with a total value of about two billion German Marks) were stored in about 700 - mostly secret - places and had to be rotated according to their expiry dates. This whole procedure including the value of the goods cost about 200 million German Marks per year and was financed by the Federal Government of Germany. It lasted until the fall of the Berlin Wall in 1989. 41 In 1950 the municipality of West Berlin received the right to operate a part of the airport buildings for civil transportation (Bezirksamt Tempelhof 1998, p. 138) as a precondition to starting the civil use of the airport. The departure hall was still partly demolished from the war (see Fig. 16). As the US Air Force was using the hangars on the eastern side of the hall the Berlin Airport Agency was permitted to build a small annex to the section next to the southern hangars, to serve as departure hall, which was officially opened at the 9th of July 1952. This part could be accessed from Tempelhofer Damm and there was enough space outside this part to serve as a car parking area. According to the Four Power Status agreement only civilian airlines of the three allied powers (USA, Britain, France) were allowed to use the air corridors to Berlin. Therefore only Pan American World Airways (PanAm), which had taken over American Overseas Airlines (AOA) in 1950, British European Airways (BEA) and Air France (AF) provided flights from and to Berlin. All three airlines used Tempelhof Central Airport, BEA from 1951 and the others from 1950 (Przychowski 1996, p. 28). Between 1953 and 1957 a remarkable campaign to help poor children, either of East German (GDR) refugees or of West Berlin residents, to spend holidays with German and American guest families in the Federal Republic of Germany was carried out with the help of the US Air Force. This campaign called “Kinderluftbrücke” was initiated by the German radio station “Nordwestdeutscher Rundfunk” and organised in cooperation of the foundation “Hilfswerk Berlin”, the Senate of Berlin and the German Red Cross. The US Air Force provided the planes, the crew were volunteers from the US Army. Within five years about 10,000 children were flown out from and back to the military section of Tempelhof Central Airport (Freundt 2001, p. 29). The development of civil air traffic grew rapidly in West Berlin. Between 1951 and 1961 the number of passengers travelling to or from Tempelhof airport increased five fold (see Annex A: development of air traffic). The small departure hall (260 square metres) from the beginning of the 1950s, which was not as well connected to the ground services as the original departure hall (5,000 square metres) with its location in the centre, reached the limits of its capacity. In 1959 the Senate of West Berlin received permission to restore the still-damaged original departure hall. It took another three years before the departure hall could be put into operation for the first time on July 2, 1962 (Bezirksamt Tempelhof 1998, p. 139). 42 The reconstruction changed the original design in a number of ways. The entrance hall was divided into two separate storeys by a new ceiling, and equipped with a porch. In the departure hall a new false ceiling was put in 4 metres below the original stucco one and a heating system of ceiling mounted hot water radiators installed (Bezirksamt Tempelhof 1998, p. 284; respondent Eberhard table 3 and questionnaire 6, Annex B). The ceiling was a similar detached rectangular grid-roof as before but without the decorative elements. Instead the single “waffle slabs” were equipped with indirect illumination. The floor of the departure hall, which originally had been designed in a pattern with four different colours as is still to be seen in the entrance hall (see photo on front cover: first row right), received a simpler beige design. The glazed view onto the apron and the airfield was blocked by the new airport restaurant, with access from the visitor galleries on the first floor of the hall. After the construction of the Berlin Wall in August 1961, the number of passengers dropped, reducing by 18% from then until November 1961. In response, the government of the Federal Republic of Germany decided to subsidise Berlin flights from March 1962 onwards (Przychowski 1996, p. 44) and the numbers went up again and reached their highest number ever with 6,121,406 passengers in 1971 (see Annex A). The capacity of the terminal had been planned for 4 million passengers per year (Bezirksamt Tempelhof 1998, p. 139). The growing air traffic increased the exposure of local residents to the noise of the planes, and this was made worse as maintenance ground checks with running engines were done during the night. To compensate, the houses along Tempelhofer Damm and nearby streets were equipped with sound protecting windows. In the middle of the 1960s another limiting factor became evident. The newly developed jet airplanes required longer runways which Tempelhof airport, because of its restricted inner city location, could not provide. After an evaluation of the different airports in the city, the Berlin Airport Agency decided to develop Tegel as new main airport of West Berlin. The construction works began in spring 1969. “Ostpolitik”, a series of political developments from the end of the 1960s adoption of the “Transit Agreement” 29 28 led to the in May 1972. This agreement greatly 28 Known as “Ostpolitik” and strongly connected with the former chancellor of the Federal Republic of Germany, Willy Brandt, is characterised by the principle “Change through Rapprochement” and improved east-west relations in the divided Germany. (http://en.wikipedia.org/wiki/Ostpolitik, Cited 08/07/2007) 43 influenced air traffic to and from West Berlin as it guaranteed surface transport access to West Berlin. Trains or road vehicles travelling between West Germany and West Berlin could now travel with fewer official restrictions. In the following years this led to a decrease in air passenger numbers as road and rail travel was cheaper, usually required less advanced planning, and permitted more luggage. Between 1971 and 1974, which was the last year before Tempelhof Central Airport stopped operating as civil airport (until 1982) passenger numbers dropped by 30% while the number of passengers travelling with cars in the same time increased by about 25% (Treibel 1992, p. 70). The offer of cheap charter flights for holidaymakers leaving from West Berlin started in 1966, and from 1967 onwards all the charter flights were operated from the old Tegel airport. This was the start of the move of air services from TCA II to Tegel. The new Tegel airport was inaugurated in October 1974, and from June 1, 1975 all the civil air traffic of West Berlin was carried out from the new Tegel airport (Treibel 1992, p. 69). Tempelhof airport was closed as civil airport and returned to being exclusively a US military airbase. In 1981, civil air services were re-started from Tempelhof airport with air taxi flights and from 1985 on the airport was opened again for reduced numbers civil flights, in the first years only for regional connections mainly to southern Germany but later to other European cities as well. After the reunification of Germany in 1990, the passenger numbers increased from 151,000 in 1991 to a peak of 1,124,000 in 1993. From then on they dropped again due to the uncertain future of the airport’s legal status, dropping 635,000 in 2006 (data source Arbeitsgemeinschaft Deutscher Verkehrsflughäfen, http://www.adv-net.org/de/gfx/index.php, Cited 12/07/2007) TCA II as a gate to freedom Before the construction of the Berlin Wall in August 1961, refugees from East Germany (GDR) who had crossed the still open border to West Berlin were usually flown out of Tempelhof Central Airport. In times of political crises in the Eastern European (Warsaw Pact) states, such as the uprising of 17th June 1953, a protest by 29 “The Transit Agreement of May 1972 guaranteed access to and from West Berlin from West Germany (the Federal Republic of Germany (FRG)), secured the right of West Berliners to visit East Berlin and East Germany (the German Democratic Republic (GDR)) and also secured the rights of FRG citizens to visit the GDR, but only in cases of family emergency.” (http://en.wikipedia.org/wiki/Transit_Agreement_%281972%29, Cited 08/07/2007) 44 East German workers against the increase of work quotas for industrial production by 10%, or the Hungarian Revolution in 1956, the number of refugees increased noticeably and this influenced the passenger numbers at TCA II (Demps 1998, p. 110). Because of factors such as its proximity to Poland (about 70 km) and its easily visible and identifiable features from the air, Tempelhof Central Airport became a target for Polish refugees hijacking planes. Between 1978 and 1982 eight planes of the Polish National Airline, LOT, were hijacked and forced to land at TCA II 30 . In addition, eight small private planes from aeronautical clubs in Poland succeeded in flying out of Poland and landing at TCA II between 1982 and 1987 (Freundt 2001, p. 152 – 153, Demps 1998, p. 117). For those refugees who had succeeded in crossing the Berlin Wall from the east to the west and wanted to leave the city, as well as for spies who had been exchanged between the east and the west, TCA II was the gate to freedom. The official end of the Cold War for TCA II With the official reunification of Germany on the 3rd of October 1990 the nominal military occupation of Berlin ended. The final peace treaty - signed at the 12th of September 1990 by the four wartime powers and the two German governments – had restored Germany’s sovereignty including its sovereignty over its airspace. The days of the air corridors were over, and with them the restriction whereby only civil aircraft of the three Allied powers were allowed to fly to the West Berlin airports. In July 1993 the US Air Force officially handed over the former military part of Tempelhof airport to the German authorities. 2.4 The use of Tempelhofer Feld for special events and leisure 2.4.1 Military parades In the 18th and 19th centuries Tempelhofer Feld was the location for large parades in the presence of German and foreign rulers – events that attracted a lot of spectators from the nearby town of Berlin and the surrounding villages. The last parade at Tempelhofer Feld took place in 1914 (Bezirksamt Tempelhof 1998, p. 13) in the 30 The abbreviation of LOT was “translated” into “Landed on Tempelhof” by the US Americans or to “Landed ooch Tempelhof” in Berlin slang. 45 presence of the German emperor Wilhelm II. Military exercises continued to be held there until 1918. 2.4.2 Leisure and political activities Apart from these military events, the area of Tempelhofer Feld was used by people from the densely populated nearby neighbourhoods, and from other parts of Berlin, for weekend leisure activities such as picnics and games, to fly kites (Bezirksamt Tempelhof 1998, p. 17), and for sports like cricket, football and tennis in summer and ice-skating in winter (Jedelsky 1995, chapter 2.1). The nearby breweries, beer gardens and restaurants offered food and drinks and other amusements like dance floors with live music. The 1895 map of Tempelhofer Feld (Figure 1), as well as the street plans from 1906 and 1926 (Annex C), show the locations of these activities in the surroundings of Tempelhofer Feld. Tempelhofer Feld was also used for political demonstrations like the annual 1st of May demonstrations. “From the end of the 19th century onwards, the field also served as a multipurpose open space for sports contests, workers’ demonstrations and Sunday leisure activities.” (Drieschner 2005, p. 100) 2.4.3 Flight shows From the beginning of aeronautics, flight experiments and shows attracted a lot of spectators. Airport companies used the marketing of this entertainment factor as an additional source of income. They provided stands and facilities for spectators at special events, and also for visitors to see the regular air traffic. “During the 1920s and 1930s, airports attracted far more spectators than actual air travellers, still a glamorous and wealthy elite. All were designed to integrate viewing platforms for these massed spectators, for ‘aeronautical propaganda’ or for nurturing ‘civic air-mindedness’ as the speeches and competition briefs put it.” (Hawkins / Lechner / Smith 2005, p. 2) The Berlin Airport Agency organised flight shows at Tempelhof airport from 1924 onwards. Already in 1925 the events attracted up to 500,000 spectators (Bezirksamt Tempelhof 1998, p. 48). The first main airport building included the Mitropa 46 restaurant, an elegantly decorated location with a big roof terrace from where visitors could overlook the airfield, and also areas equipped as beer gardens next to the main building where people could sit outside in summer and watch the shows or the scheduled take-off and landing of planes. Fig. 20: Flughafen Tempelhof / Mitropa Flughafen Restaurant, Aufn. 20/06/1933, (T3/1621 © Museen Tempelhof- Schöneberg/Archiv) The flight shows included artistic flight performances by famous pilots, formation flights, entertainment for children, flight competitions, presentations of famous aircraft or of the latest models, flight competitions and other activities. The flight show events were continued when the Nazi government came into power but used for propaganda purposes as well as to demonstrate the power of the new government and the strength and abilities of the new German Air Force. For example, at a flight show in June 1934 the attendance of the Minister for Aviation, Hermann Göring, was announced at the adverts (Bezirksamt Tempelhof 1998, p. 51). 2.4.4 Political demonstrations The airfield of Tempelhof Central Airport was also used by the Nazi government for political demonstrations like their First of May parades. The Nazi’s successful use of perfectly arranged and staged mass events for propaganda purposes is notorious. To meet the demand for this important aspect of the use of the airport, the design of the new airport included space for 65,000 spectators on the roof. Thirteen massive stair towers continued upwards from the second floor for the specific purpose of 47 giving access to the roof. Together with the stands to be provided at the edge of the airfield this “air stadium” would have been able to hold up to one million spectators (Drieschner 2005, p. 104; Jockeit / Wendt 2005, p. 161). 2.4.5 The open house events of the US Air Force From 1948 until 1992 (Bezirksamt Tempelhof 1998, p. 134, Freundt 2001, p. 143) the US Air Force organised annual Open House events at Tempelhof Central Airport; in the beginning these were only for a selected group of people but from 1952 on were open to the general public. For thousands of Berliners, including many Neu-Tempelhof residents (see Table 2: summary and questionnaires Annex B), the open house events at TCA II were exciting and interesting. For the technical and military enthusiasts it offered an opportunity to have a look at the latest technology or the biggest airplanes of the time. For families it provided a spectacular event with parades, fly-pasts by the planes, shows, exhibitions, movies, music and American food such as ice cream and popcorn. It was a performance of the “American Way of Life”. In 1973 – the 25th anniversary of the Berlin Airlift – a veteran plane from the Airlift (a C-54-Skymaster) was flown to TCA II, and in a ceremony was named “Rosinenbomber” (raisin bomber), the name given by Berliners to the planes of the airlift. It was left on display at the airfield near Columbiadamm as a monument. In 1974 the event included the space vehicles Mercury and Apollo, and the Skylab space station, and attracted more than 320,000 spectators (Bezirksamt Tempelhof 1998, p. 135). 48 Fig. 21: Flughafen Tempelhof “Tag der offenen Tür” Aufn. 1970 (T24_06) (© USA AirForce) After the reunification of Germany, the German Air Force also participated in the open house events and at the last open house in 1992 a delegation of the Russian Army visited the event with a helicopter (Freundt 2001, p. 141). This was another link in the long the tradition of Tempelhofer Feld since the 18th century: military parades attended by representatives of foreign powers, a site for attractions and events like flight shows and spectacles. 2.5 Tempelhof Airport as recognised heritage 2.5.1 Historical monument status Since 1994 Tempelhof Airport has been listed as a monument according to the Law for the Protection of Historic Properties in Berlin. As a consequence, a survey and inventory report of Tempelhof airport was commissioned by the Berlin Senate for urban development, and carried out by consultants Handrack/Jockeit Office for Architecture and Urban History, in 1995. Based on this report, the Berlin Airport Agency, as representative of the owners, in 1988 commissioned from the same consultants a maintenance plan, in accordance with the historic properties law paragraph 8, section 3. According to the law this plan can be legally binding: 49 “Within reason, historic properties are to be preserved and cared for in accordance with these historic property maintenance plans.” (Law for the Protection of Historic Properties in Berlin, § 8, (3) sentence 2, Berlin 1999, official English version of the law). 2.5.2 European heritage In 1999 a cultural project entitled “L’Europe de l’Air”, was initiated by the French Ministry of Culture. This was a cooperative project between the French Ministry, English Heritage (a government department) and the heritage department of the city of Berlin, and was supported and partly financed by the European Commission’s Raphael programme. “The aim of this project, launched in 1999, is to create an international network of specialists concerned with the study and preservation of historic airports, some of the most significant and emblematic places of Europe’s twentiethcentury heritage.31” The project organised international workshops in Liverpool (1999), Berlin (2000) and Paris (2001), the locations of the three reference airports Speke, Tempelhof and Le Bourget, and in 2005 published a book with its findings which has been used as a reference for this thesis (Hawkins / Lechner / Smith 2005). With this nomination as part of the cultural project “L’Europe de l’Air,” Tempelhof Airport has been recognised as part of the cultural heritage of Europe even though there exists no formal procedure for this recognition. The initial work that was done to develop the conservation plan has been praised as an example for a good approach to protect and maintain the heritage, but this valuable documentation appears to have been left unused. The conservation plan is stored at the archives of the Heritage Department of Berlin. 3 Significance of the site “The whole is more than the sum of the parts”. To define the heritage of Tempelhof Airport, it is necessary to distinguish between characteristics that are related to the building and its architecture, and 31 www.euonair.european-heritage.net/uk/acc2.htm, Cited 22/05/2007 50 characteristics of the site as such. Tempelhof Central Airport (TCA II) consists of the buildings and the airfield, both designed by Sagebiel. Those are the components of the site visible today. To be able to identify and value the significance of the site as a whole it is necessary to analyse the different layers of perception connected to TCA II. Four different general perceptions of Sagebiel’s Tempelhof Airport complex can be identified. 3.1 TCA II as architectural design In the 1930s the rapid development of air traffic throughout Europe and in the United States of America, and the problems this caused at existing airports, led to a discussion about a better airport design and to specialisation in this field. “The manifest complexity of the airport as a system encouraged the development of specialised architectural firms: Norman and Dawbarn in Britain, Ernst Sagebiel in Germany or Delano and Aldrich in the United States.” (Voigt 2005, p. 17) With the design of TCA II, Sagebiel further developed the functional concept of airport buildings by separating the different functions on different levels, and this additionally permitted the provision of boarding for passengers under a protective roof. The whole organisation scheme of the airport, including the linkage with the ground transportation systems, became more efficient and in a way more industrialised. The architecture of the building in general with the impressive cantilever construction of the canopy - which in itself is a masterpiece of engineering - is a fine example of innovative new airport design in the 1930s. 3.2 TCA II as example for the Nazis’ use of architecture The building itself, because of its size and architectural style, its strongly geometrical axis-symmetrical design, and its place in the overall planning for the new German capital Germania, can be understood and interpreted as an example of the Nazis’ use of architecture to demonstrate their demand for power. The Nazis, for political reasons, intended to build the biggest, most beautiful and most important airport of the world. “The Nazis, with the laying of the foundation stone, already celebrated the building complex as the future aviation hub of Europe, underlining the fact that it 51 was to be the largest airport on the continent. Within the Nazis’ way of reasoning, the issue of the size of a site and its ability to withstand any comparison, suggested their strength and showed their use of architecture as a way to demonstrate their demand for power.” (Schäche 1996, p. 11932, translation by the author) The “command based” hierarchical (even totalitarian) approach to planning and building, by over-ruling or ignoring existing democratic structures such as the municipality and the Berlin Airport Agency, was one of the characteristics of the Nazi government (Schäche / Reichhardt 1985, p. 23). The mixture of architectural styles, with very regular and symmetrical stone covered façades facing the city on the public side of the building and an airfield façade in a Bauhaus-like technical design with steel framed doors and windows, is typical of the Nazis’ use of architecture. After the Second World War, the events and memories of the Nazis were blocked out and repressed in Germany. In the context of architecture – even though the official buildings designed for the Nazi government were present in the main cities – there was little or no research done in this field. The later publications about architecture in the Third Reich either simply described the buildings without analysis of the political context (Schäche / Reichhardt 1998, p. 10), or the subject as such was regarded as “Nazi architecture” in general and therefore to be disqualified and not be written about. An example of the latter is the attitude of the well-known historian of architecture Sir Nicolaus Pevsner 33 who chose to not write about the topic. However, according to more recent research the Nazis used different architectural styles according to the purpose of the buildings (Schäche / Reichhardt 1985, p. 11 – 12). A classical style was used for their official buildings (for example Reichskanzlei, Reichsluftfahrtministerium in Berlin), a modern Bauhaus like style for industrial buildings (for example the Heinkel Werke Oranienburg by Herbert Rimpl), and a 32 „ Die Nazis feierten die Anlage bei ihrer Grundsteinlegung bereits als das zukünftige „Flugkreuz Europas“ und hoben die Tatsache hervor, daß es sich hierbei um den größten Flughafen des Kontinents handelte. Die Frage der Größe einer Anlage und der Vergleichbarkeit waren in der Argumentation stets Suggestion der eigenen Stärke und machten somit die Indienstnahme der Architektur als Materialisierung des Machtanspruchs deutlich.“ 33 Sir Nikolaus Pevsner, (* 30/01/1902 in Leipzig –† 18/08/1983 in London), German-born British historian of art and architecture, in his book „Europäische Architektur“ commented on Nazi architecture: “Was die nationalsozialistische Architektur in Deutschland angeht, so ist jedes Wort über sie zuviel.” (Schäche / Reichhardt 1998, p. 9) 52 more modest and old fashioned style for their settlements. This old fashioned style used small windows, steep pitched roofs, plastered façades, rural ornamentation and local construction methods and materials following the ideas of the so called Heimatstil. Examples include the settlements along Grazer Damm in Berlin Schöneberg designed by Speer’s architectural office, and Waldsiedlung Krumme Lanke (former “Kameradschaftssiedlung SS”) in Berlin Zehlendorf, designed by the planning department of the non-profit housing association for employees “GAGFAH” (Gemeinnützige Aktiengesellschaft für Angestellten-Heimstätten). This implementation of different styles according to purpose – as explained above – is underlined by the same architects designing in different styles for different purposes. Examples include Albert Speer with his monumental Germania buildings on the one hand and the Heimatstil settlement on the other hand, and Herbert Rimpl with the industrial buildings for Heinkel (German airplane producer) and the settlement of Leegebruch for the employees of the Heinkel factory in Oranienburg near Berlin. Tempelhof Central Airport itself unites two different styles – the monumental and the industrial – in one building. 3.3 TCA II as a symbol for friendship The Berlin Airlift was one of the most important events for the divided city of Berlin as the blockade, and the political situation that led to it, endangered the very existence of West Berlin and threatened the citizens who had only recently survived the bombing and the battle for Berlin in the last days of the Second World War. When the blockade started it was not at all obvious to the inhabitants of West Berlin what the outcome was going to be. The feeling of being defeated was prevalent. How the western Allied powers, until recently enemies of Germany, would respond to this challenge was not generally known. In the event, the three western Allied Powers decided quickly. In a combined military and civilian effort, they started the Airlift, using to their advantage the functional building complex at Tempelhof airport, to support the West Berlin population and provide them with food and other essential supplies. The reasons for this decision were political. The western powers wanted to implement their ideas for post war development in Europe and to strongly resist the perceived threat of Communism. 53 Therefore the Airlift was a demonstration of the power and determination of the Allied Forces and their political leadership. Apart from these political reasons there was also the humanitarian aspect, which in the long term seems to be the dominant one in the perception of the public. For example, Gail Halvorsen, one of the US Air Force pilots taking part in the airlift and later, in the 1970s, commander of Tempelhof airbase, related in his autobiographical book “The Berlin Candy Bomber” that this was not an easy task for him as a soldier, and he did not know beforehand how he would feel about helping former enemies. But when he saw the misery of the people in Berlin he no longer perceived them as enemies and, according to his account, the same was true for most of his fellow soldiers and airmen as well. The dramatic events and direct support of the Berlin Airlift were important in the transformation of the feelings and perceptions of the people of West Berlin from being defeated to being protected, and their view of the three western allies from being their enemies to being friends. As the US Air Force contributed the major part of the flights (see chapter 2.3.2.2) and Tempelhof Central Airport was their air base and main airport for the Airlift, the name of the airport is permanently connected with this event and is often associated in public opinion with friendship and support. 3.4 TCA II as a gateway to freedom during the Cold war For thousands of refugees who came from the Eastern bloc states to West Berlin before the construction of the Berlin Wall, as well as for those who managed to cross the Wall after it was built in 1961, Tempelhof Central Airport was their gateway to freedom. The Soviet Union respected the agreement about the air corridors. Therefore, as soon as the refugees had reached West Berlin they could be sure that they were safe and could travel onwards to their final destination via TCA II (until the new Tegel airport opened 1975). This positive image of the airport was enhanced by fact that until 1975 TCA II was the main airport of West Berlin where all politicians and VIPs landed and thereby avoided having to pass through the GDR border controls. 54 3.5 Other significant aspects Apart from perceptions directly related to the building complex itself (discussed above), the following aspects also form an integral part of the heritage and add to its significance. The location of Tempelhofer Feld has a century old tradition of use as military exercise place (see chapter 2.1) and leisure ground, sometimes the two purposes were combined in military parades, intended as an opportunity to show off and impress, which were public events where people used to go with their families. At times the parades were attended by foreign dignitaries which increased the attraction for the local population of Berlin and the surrounding villages. Tempelhofer Feld also has a history of use for out door leisure activities. People from the nearby city districts used to go to Tempelhofer Feld on Sundays with their families to have a picnic at the then outskirts of the town, and to play games. Another aspect of the site of Tempelhofer Feld was its use as aviation field for experiments and testing, again in combination of military and civil use, and as a location for flight shows and other spectacular aviation events like the touch-down of Zeppelin airships or the arrival of the first German pilots who flew across the Atlantic ocean. This tradition was revived again from the 1950s on when the US Air Force started with the organisation of Open House events. In addition to its use for both military and leisure purposes, Tempelhofer Feld was a stage for political demonstrations of workers, which the Nazi government took over in 1933 and organised as their 1st of May Parade at Tempelhofer Feld (Bezirksamt Tempelhof 1998, p. 51). These popular and military traditions and functions are connected to the site itself and not to the building complex or airfield of Sagebiel. 55 4 Problems of preserving and conveying historical events and their values 4.1 Preservation of material values In chapter three, the values that characterise the significance of the heritage site of Tempelhof Airport have been identified. For the material items that are connected with a building, its architecture and construction, there now exist detailed methods to describe and preserve them as soon as they are under protection. In case of Tempelhof Central Airport a thorough inventory - which is one of the prerequisites of preservation - has already been carried out, along with detailed mapping, to document the state of the building. This includes identifying which parts are original and which parts have been changed over time by the different users 34 . The “Law of the Protection of Historic Properties in Berlin” in its second paragraph “General Preservation Regulations” § 8 (3) also provides measures as to how to maintain protected buildings and suggests the creation of a maintenance plan if required by the Historic Property Authority. The same office which carried out the inventory of TCA II was commissioned with drawing up a maintenance and conservation plan (see section 2.5.1). The authors of the plan, Jockeit/Wendt, summarised it for the international workshop of the cultural project “L’Europe de l’Air” (see 2.5.2). 4.2 Preservation of non-material values Perhaps a more challenging question than the preservation of material items, is how to preserve non-material values: which methods are available to convey significant historical events connected to a building or site in an authentic way? Erecting a monument is a long-practised and common method to achieve the aims of recording historical events and attracting people’s attention to them. However monuments are not context-neutral and often use symbols and have particular connotations which strongly relate to the time and the prevailing cultural background 34 „Flughafen Berlin-Tempelhof, Erfassung und Bestandsaufnahme der Denkmalsubstanz Band I und II” on behalf of Senatsverwaltung für Stadtentwicklung und Umweltschutz, Landesdenkmalamt 56 of when they were built. Over time they can lose their symbolical value, or the symbolism can be differently interpreted, or not be understood any more. For example the abstract concrete memorial to the Berlin airlift even now – only some 60 years after the event – may well puzzle some people, especially if they are not residents of the former West Berlin, instead of reminding them of the Airlift and those who made sacrifices to ensure that West Berlin was supplied. Another way to preserve non-material values is to describe and illustrate events with the help of artefacts of the time and statements of contemporary witnesses (interviews, letters, books) and other contemporary sources such as newspapers, radio, TV or film records of the event. For obvious reasons the further events lie in the past the more difficult it is, in general, to provide these means. The feeling of authenticity will usually be enhanced if any artefacts and documents can be presented at the original site. The presence of a building or site where historical events took place can trigger the imagination of people, give first-hand experience of some parts of the physical context, and enable visitors to understand better the historical and emotional context. A further issue of interest is, if - and how - the presentation of historical heritage sites is influenced by intentions and perception of the institutions which are responsible. Recent research on American National Monuments (Schindler 2003) includes evidence that the presentation at three important USA historical sites has undergone quite important changes during recent years, and investigates the reasons for this. The way visitors were addressed, and which members of American society of the historic time of the monument were presented as being of interest to visitors, had changed. The monuments represent important events in American history but initially focussed only on some parts of American society and neglected the contribution of other parts of society. The research showed that the focus had broadened and become more inclusive over time In the case of Tempelhof Central Airport a full and balanced presentation of the history of the Airlift and the Cold War would probably need to include the perspective of the residents of East Berlin and the Soviet Union on these events as well as West Berlin and the Allies. 57 5 Heritage in the context of the World Heritage Convention 5.1 Definition of the heritage of TCA II To achieve a better understanding of the heritage of TCA II, different aspects concerning Sagebiel’s airport (building complex and airfield) have been described and analysed in the previous chapters according to their significance for heritage: the history of the location Tempelhofer Feld, the initiation of the first airport which prepared the ground for TCA II in Weimar times, the concept and construction of the building as well as the historical events connected to it. To complete the view a small number of local residents were interviewed as witnesses about their experience with and their perception of the airport. In accordance with the World Heritage Convention (see chapter 1.2) a viable definition applicable to the heritage of Tempelhof Central Airport which covers the different aspects as mentioned above could be: Architectural work with historical and artistic value, example of a type of architectural and technological ensemble which illustrates a significant stage in human history, directly or tangibly associated with events. From the list of attributes for the authenticity of a cultural heritage site mentioned in the Convention the following would be applicable to TCA: Form and design, materials and substance, use and function, traditions and techniques, location and settings and as well spirit and feeling as indicators for the character and sense of place. The Convention recommends the following information sources to find out about the nature, specificities, meaning, and history of the cultural heritage: all physical, written, oral, and figurative sources. For the purpose of this thesis only those values and their attributes applicable to TCA II will be further analysed - the case of this heritage site has been presented and will be used as example. 58 5.2 Analysis of the values The values mentioned above can be categorised in the following way: - Values related to the physical appearance – the architecture of a building in its location and setting. These values can be experienced visually through direct perception: a building with its dimensions, form, style, construction, materials and substance, situated at a certain place. The significance of such a building as heritage implies a ranking in comparison with other buildings of the same type, architectural style etc . In this case physical or tangible attributes in combination with knowledge as ranking requires knowledge- determine the estimation. Example: TCA is still one of the biggest buildings worldwide. - Values related to the historical context of a building or a site: If a building or a site has been involved in important historical events or a significant period in human history the factor or factors relevant for heritage value is not necessarily the architecture of the building but the connection with the historical event or time – transferred through the memory of people during their lifetime or through knowledge about the history by later generations. The perception and the estimation of the building therefore are affected by immaterial or intangible attributes (memories and/or knowledge). Example: the location of Tempelhofer Feld was an important stage for the early attempts of aviation, TCA II was the main airport of the airlift and until 1975 the main airport of West Berlin. - Values related to the use and function of a building or a site: The purpose of a building, if it was, or still is, used for example for cultural or technical functions (a church, station, airport, factory etc.) is another intangible criterion that influences a building’s perceived value in connection with knowledge and ranking. Example: TCA II is the oldest inner city airport still in operation, it illustrates the development of functional concepts of European airports in the 1930s. - Values related to the character and sense of place of a building or a site: Character and sense of place of a building are probably the most difficult and contradictory issues as they depend on feeling and spirit, ideas which are subjective and might be perceived according to individual taste or changing 59 societal values. However, feelings connected to a building or a site are influenced as well by personal experiences and knowledge about the history of the building and events that took place there. Architecture and style can evoke or enhance feelings in the viewer. Example: TCA II for some architectural critics has been so strongly related to Nazi Germany that they - in an emotional reaction - did not want to treat it as an architectural work. TCA II was designed to demonstrate Nazi Germany’s superiority by impressing people with its architecture. And even though the Nazis’ assertion has been proved wrong very quickly in the course of history, the building complex still impresses people. A closer look at the values analysed above shows that they all have material and non-material components. The estimation of the heritage is based on tangible and intangible aspects which depend on each other and can barely be separated. Without knowledge about the historical background in general and the special history of art, architecture and technology – depending on the type and function of a building or site – estimation of heritage value is difficult if not imposible. In the World Heritage Convention a variety of sources, including oral sources, are recommended to achieve this knowledge to illustrate and explain the special character of a cultural heritage site. These oral sources are the living memory of people who experienced and witnessed the development of the building and the historical events connected to it. They will be lost if they are not recorded or passed on as part of an oral tradition, within the lifetime of the witnesses. 60 5.3 Classification of the terminology “tangible” and “intangible” As the term “intangible heritage” has become quite a keyword during the last years, a short explanation will be given to distinguish between the intangible aspects of a heritage site according to the World Heritage Convention (adopted in 1972) and the intangible cultural heritage of the Convention for the Safeguarding of the Intangible Cultural Heritage (adopted in 2003). The term “intangible cultural heritage” was first mentioned in the Mondiacult World Conference on Cultural Policies 1982 in Mexico City. During the following years it became evident that there was a growing need to protect “Non physical heritage” or “Traditional Culture and Folklore”. In article 2 of the Convention for the Safeguarding of Intangible Cultural Heritage the “intangible cultural heritage” is defined as: “ the practices, representations, expressions, knowledge, skills – as well as the instruments, objects, artefacts and cultural spaces associated therewith – that communities, groups [...] recognize as part of their cultural heritage. This intangible cultural heritage, transmitted from generation to generation, is constantly recreated by communities and groups in response to their environment, their interaction with nature and their history, and provides them with a sense of identity and continuity.35 The Intangible Cultural Heritage is manifested inter alia in the following domains: oral traditions and expressions including language; performing arts; social practices, rituals and festive events. In this case the heritage itself is intangible even though it can be practiced with the help of material objects like artefacts. It is performed in a group of people and transmitted from generation to generation as part of their cultural identity. The cultural heritage as defined in the World Heritage Convention is always a material object: a building, piece of art, etc, whose significance as heritage arises from values which are defined by both tangible and intangible aspects. 35 http://www.unesco.org/culture/ich/index.php?pg=00006, Cited 19/06/2007 61 6 TCA II in the perception of local people 6.1 The survey To investigate how the significant values of Tempelhof Central Airport, identified in chapter three, have been perceived by local people and how these perceptions have altered over the course of time, a small survey was undertaken. Interviews were carried out with long-term residents of Neu-Tempelhof who had been firsthand witnesses to the construction and evolution of TCA II and who had also lived through the airlift and the times of the Cold War. Chapter four has already introduced the concept that statements of contemporary witnesses can be used to describe historical events in an authentic way. In chapter five the importance of tangible and intangible aspects for the estimation of heritage and the interdependency of these aspects has been analysed. The research based on the interviews was intended to provide information about whether and how, tangible and intangible aspects, influenced local residents’ perception of TCA II. As the author had been living in Neu-Tempelhof since the beginning of the 1980s she was able to identify a number of elderly residents of the district who had either been born in this part of the city, or had spent a significant span of their lives in the area, so that they had considerable experience of living next to, or near to, the airport. The range of interviewees intentionally did not include people who moved in to the area after Tempelhof Airport had been largely closed down for regular air services in 1975, in order to avoid biasing the results. Another precondition was the age of respondents. As it was important to go back to the times of the Third Reich (the time of the construction of the airport) to receive first-hand information, it was necessary to find residents born well before 1935 so that it was possible that they would have some memories of that time. In the end 11 residents answering the above criteria were identified who were willing to be interviewed. All but one (due to time constraints) were questioned in their own houses or flats. All of them gave their consent to publish their full names. Some respondents provided the author with books, magazines and other documentary items like postcards relevant to the topic to assist with the process of understanding their perceptions of the airport. The process of interviewing all eleven volunteers was completed in six weeks. 62 During the course of the interviews the respondents related many interesting stories and first hand anecdotes, however, the focus of the interviews was specific information gathering on the topic of the study. The interested reader is referred to Annex B where brief details of some of the anecdotes are given in the interview language, German. 6.1.1 The questionnaire The interview to answer the questionnaire was carried out in German. The complete set of the original data can be found in the Annex B. An English summary is presented in table 3 (see next page). In this table the airport is referred to generally as TCA. This covers TCA I and TCA II because the memories of some of the respondents go back to the first airport TCA I. The questionnaire is divided into five major sections of which each contains a set of questions. The first set of questions asks for information about the interviewee, his or her name, year of birth, since when they have been resident in Neu-Tempelhof, and if he/she has been a user of the airport. The second part is about his or her personal experience of Tempelhof Central Airport, first memories and impressions and further encounters, subdivided into different categories, including: experience as a flight passenger, as a visitor and of special events which were identified. The third part asks questions about the respondents’ attitudes towards the airport, if they are enthusiastic about flying, interested in aeronautics and aviation technology, if they feel disturbed by the noise of the air traffic and/or emissions, or if they are just not affected or are indifferent towards the airport. The questionnaire asks about any specific changes in their perception and - if there have been changes – the causes for the change. The fourth set of questions aims to find out about the respondents’ ideas and perceptions regarding Tempelhof Central Airport, for example whether they see it as a Nazi building, or mainly connected to the Airlift, as a technical or architectural monument, or just as a functional traffic building. The fifth part deals with the respondents’ view on heritage connected to Tempelhof Central Airport and their ideas and suggestions for a future use of the site. 63 Table 3: Summary of the results of the questionnaire (translation by the author) Name 1 Sex Year of Resident in Flights birth Neufrom Tempelhof TCA First memories connected to TCA 2 Further encounters with TCA 3 Attitute towards TCA enthusiastic about flying, not molested by air traffic noise, impressive because of its but sympathetic with people size who are effected positive attitude towards the imposing building airport (husband was a pilot) Erika f 1920 since 1964 yes no specifiic memory regular visits to the airport with family fo watch air traffic and VIPs;

The range for the year of birth lies between 1920 and 1959. Five of the respondents were born before 1935, four in the 1940s and two in the 1950s. Ten of the eleven persons currently live in Neu-Tempelhof, all respondents had lived at least 20 years in the area, and one of them as many as 80 years. None of the persons questioned lived directly under the flight path, but nine out of the eleven lived less than one kilometre distance from the Airport perimeter (see aerial photo, Annex D). Only one out of eleven persons had never flown to or from Tempelhof Central Airport. Questions section 2: Interviewees were asked about their first memories related to special events at TCA: this issue for nine of the residents is clearly combined with childhood memories, only two of the interviewees did not have specific first memories and both of these had moved to Neu-Tempelhof as adults. Within the nine interviewees boys tended to remember specific instances of special events while girls remembered more general events. This may be partly, or entirely, due to gender issues. At that time (between the 1930s and the 1960s) it was more likely for boys to be interested in aeronautics and planes and military equipment than for girls to be interested in these. Therefore they were probably more eager to visit the special events at the airport 36. 36 One example of a special event as first memory of TCA was related by Hans Joachim. It dates from when TCA I was still in use and considerately influenced his life. In the 1930s at the age of about 12, with a group of other boys he watched a plane landing and noticed that something fell from the plane. So they all went to look at what it was and found a cockpit window in a tree. He climbed the tree, picked up the window and carried it home as a trophy. Later in the day the air police from TCA I arrived at his home and took him and the window to the airport. There he was introduced to the flying crew of the plane and questioned about the incident. The crew were all glad to get back their window and he was offered the chance to choose a reward. So he asked for a trip in the plane, something he was keen on but couldn’t afford to pay for, as it cost 5 Marks (as he still clearly remembers). This was in a way the start of his career as a pilot; as a young man he was trained as a fighter pilot for the German Air Force. (for further information see Annex B, Fragebogen 3). 65 Interviewees identified three main purposes for their further encounters with the airport: the first one was to meet visitors, the second to go regularly to the airport with the family to watch the scheduled air traffic from the terminal building, the third to go for special events like flight shows in the 1930s and open house events from the 1950s until the early 1990s. The latest event recalled was the Red Bull Air Race in 2006. Only one out of the eleven respondents did not mention any further visits to the airport after their initial contact. The first two issues (mentioned by eight respondents each) are related to the usual function of the airport, the third (mentioned by nine respondents) to special events. Questions section 3: Asked about their general attitude towards Tempelhof Central Airport two of the eleven interviewees – both men - characterised their feelings as indifferent, all the others described their attitude as positive or enthusiastic. Out of the people with a positive or enthusiastic attitude, three people – all women – had undergone some change in their attitude as they started to be more aware and critical on environmental impacts of air traffic. These changes were most likely influenced by the start of the ecological movement in Germany in the 1980s. One of the women told that she started to become more environmentally conscious when she was a student, for another women the crucial event that changed her attitude was the birth of her sons. Questions section 4: This part deals with the respondents’ perceptions of Tempelhof Central Airport. Six out of the eleven respondents named just one key word to characterise their perception, four persons mentioned two and one person three key words. The top key word to characterise their perception was architectural monument (six times) followed by technical monument (four times), impressive building (twice), airlift (twice), cold war (once) and Nazi Germany (once). For the respondents, the main aspect of their perception of the site was the visual experience of the building complex. A significant majority of the mentions of key words (12 out of 16 times) were for the three terms architectural monument, technical monument and impressive building. Far less frequently mentioned (4 out of 16 times) was the understanding of the site as connected to historical events with keywords: airlift, cold war and Nazi Germany. Therefore the conclusion of the author 66 is that the direct experience of the building - the tangible aspect according to the analysis in chapter 5 - is so impressive that it dominates most people’s perception of the airport. One explanation for this phenomenon could be that most of the respondents had their first contact with Tempelhof Central Airport as children when the perception of dimensions and size of a large building is likely to be strongest. One of the respondents described her feelings when she first (at the age of twelve) got on board a plane at TCA. She was overwhelmed by the size and height of the overhanging roof and the impression made by the way that she could just go out of the departure gate and the plane was waiting right there under the roof and she was able to climb the gangway and get on board. Questions section 5: All the interviewees agreed with TCA having been listed as protected historic property. The reasons they gave as justification for the listing – this time without provided key words – range from architectural and historical values to national and international importance in connection with important historical events. That Tempelhof is currently the oldest still functioning inner city airport, was mentioned as well. When asked about the future of the airport, six out of the eleven respondents wanted to keep the airport open, four preferred to close it and one respondent was undecided. When asked for ideas for a future use of the site four residents wanted to keep it as it is now and one resident wanted to open a flying school. Four residents suggested using the site as museum such as an Air Force museum or museum of technology. Creating a park or recreational area was mentioned four times; holding trade fairs and auctions in the building complex, and using it as an office building for the Ministry of Defence were each mentioned once. 6.2 Results The questionnaire gives clues about the perception of local residents of NeuTempelhof even though the study cannot be considered as representative due to the limited number of participants. The findings represent specific, well detailed, anecdotal examples. The composition of the sample according to age, gender and background was varied and their perceptions and ideas differed. Nonetheless, some 67 useful conclusions can be drawn up about how local people have perceived Tempelhof Central Airport (TCA II) since it was built, and in particular about the difference in difficulty of capturing tangible and intangible aspects of heritage. 6.2.1 Intangible aspects of the heritage of TCA II The intangible aspects of the heritage of TCA II, the connection of the airport to events – either historical events like the Berlin Airlift or entertainment events like the flight shows and open house events - were still present in the memory of the respondents but in differing degrees of intensity. A connection to Nazi politics and ideas – which has been established in architectural and historical publications recently - was only mentioned by one respondent who moved to Neu-Tempelhof in the early 1970s. The Cold War and the Airlift were mentioned by one and two interviewees respectively. The sample of available interviewees with possible associations with the Nazi era is particularly small and it is difficult to draw conclusions: of the five respondents who, due to their age could have had first hand experience of the construction of the new airport, two came to live in Neu-Tempelhof after the war leaving only three respondents with direct childhood memories of the earliest years of the airport. Possible reasons to explain why the airport complex as a Nazi prestige issue is not important for the perception of residents may include the following: The new airport building was never officially inaugurated by the Nazi government nor even completed in that era. The old airport buildings from Weimar times were still functioning as the terminal until the end of the war. Parts of the new building complex were used as offices by the ministry of aviation, some areas were used to assemble and maintain war planes. Therefore, access to the building was subject to restrictions since it was no longer in the interest of the government to draw the attention of the public to this building37. 37 One indicator for this assumption is that even though the change of the transport connection to the airport (a new access road “Neue Flughafenstraße”) and the change and renaming of the underground railway stations (Flughafen became Paradestraße and Kreuzberg became Flughafen) are documented in the street plans of the publisher Pharus Plan of 1936 and 1944 (see maps Annex C), the new airport building does not appear at all on these maps. 68 The second reason is perhaps due to a change in propaganda topics according to the political situation. As soon as the war started the priorities of Nazi politics were focused on the management of the war - prestige projects like “Reichshauptstadt Germania” and the new airport received less attention and financial support than before. Some sources even say that Speer as the architect responsible for the development of the Reichshauptstadt had already abandoned the idea of an inner city airport - in accordance with Hitler’s wishes- as not being functional and efficient, and had expressed the idea of planning one or more big airports at the edge of Berlin. He proposed that Tempelhof Central Airport should be transformed into a leisure park for the Nazi workers’ association (Dittrich 2005a, p. 28; Hecker 2005, p. 93, Drieschner 2005, p. 104). A third reason is possibly the lack of research about the Nazis’ use of architecture, a topic which has only started to receive attention since the 1980s. The perception of Tempelhof Central Airport as a symbol for the Airlift was only third in the ranking out of five for the interviewees, a result which was unexpected. The experience of the airlift with hunger and cold and other deprivations shortly after losing a major war was potentially life-threatening for the West Berlin population. The memory of this event has been kept alive in West Berlin with annual memorial events at “Platz der Luftbrücke”, exhibitions, numerous publications and special events like the 50th anniversary of the airlift in 1998. Of the seven respondents, who due to their age experienced the Airlift, four lived in Neu-Tempelhof during that time. Of these four only one named the airport as a symbol for the Airlift. He had a threatening experience with the American military police (MP) as a boy when after a plane crash he took some milk powder from the plane, got caught by US MPs and was forced to give it back. His perception is connected to his personal experience. The second respondent who named the airlift as connected to the airport was born after the airlift. The Cold War seems to not have created a link to the airport in the memory of the interviewees. It was mentioned only once and in combination with the airlift even though two of the respondents mentioned flying out to avoid GDR border controls and seven out of the eleven went to open house events of the US Air Force. There appears to be clear dissociation of the memory of events with the interviewees’ stated perceptions. One explanation could be that for Berlin residents the Berlin 69 Wall as the visible borderline is the obvious and most dominant symbol for the Cold War which leaves little room for another symbol. Another reason might be that the Cold War lasted more than four decades and Tempelhof airport was not the location for spectacular Cold War incidents but part of the Cold War routine which offered access to West Berlin without passing through the GDR on surface transport. Whatever the cause, this clearly demonstrates that even events which are dramatic at the time, and which form part of the intangible aspects of heritage, may not always be easy to discover or document even sixty years later, and that perceptions of first-hand observers may change over a relatively short space of time. Quite unexpectedly for the author, the research on what factors influenced the perception of local residents showed very clearly that the intangible aspects of the site, the function as airport and the connection to national and world events, played very much a secondary role. From the perspective of a site, such as Tempelhof Airport, as heritage (in the sense of the World Heritage Convention) this demonstrates a very clear need to use resources to ensure that intangible aspects are not lost, and subsequent generations have only the tangible aspects available. Within a very few years no witnesses of the early days of TCA II will be left. 6.2.2 Tangible aspects: TCA II as architectural monument For the group of respondents the architectural impression was clearly the most dominant aspect of their perception. As noted in chapter 6.1.2, most of the interviewees had their first encounter with the airport as children which would tend to enhance the impression of the size and dimensions of the building. The visual sense is a powerful one. The design of the building of TCA II has recognised architectural qualities; values which people, even if they are not experts in the field, are likely to notice. This building was deliberately designed to impress people and used a variety of means to achieve this aim in an expert way. Even though the design of the whole building complex with its axial reference to the Schinkel monument on the Kreuzberg hill was not completed according to the original plan (see chapter 2.4.2) the monumental character of the part that was finished can still be experienced by a visitor. 70 The strong reaction of the interviewees to his airport building demonstrates that the architect Ernst Sagebiel has succeeded in impressing visitors to the airport with his design. The tangible aspects of the building have turned out to be the most important values for the heritage of TCA II for the interviewed residents. 6.2.3 TCA II as part of everyday life From the author’s personal observations during the interviews, a further aspect turned out to be important. This had not been included in the questionnaire design, but it was mentioned in one way or another by eight of the eleven respondents. Tempelhof Central Airport was, and for some interviewees still is, part of their everyday life. Different issues were mentioned to describe this influence. The negative impacts were the noise of the air traffic and the smell of kerosene. Not all the respondents are affected equally by this pollution. Only two out of the eleven felt troubled by the noise or smell of aircraft The noise at the end of the 1960s, when the annual passenger number exceeded 5 million and early jet passenger aircraft were far more noisy than they are today, must have been really a dominant element in the everyday life of residents and severely intrusive. At that time there were nearly 200 take-offs and landings every day. But even the noise became part of a daily routine for some of those interviewed. One of the respondents remembers that her sons, because they used to play in the garden behind her house, could distinguish between the different aircraft from their noise and got exited when the more unusual sound of a helicopter was heard. Some respondents remembered the last flight in the evening – a post flight that took off around 11 pm – or the earliest flight in the morning at about 6 am which could clearly be distinguished as the rush hour had not yet started. For some respondents the airport in the 1960s and 1970s was a regular destination for a Sunday walk with the family, or to visit the airport restaurant for special events. Apart from that the airport provided shops – particularly mentioned were a photo shop and a hairdresser - and a late night post office which residents used as well. One interviewee related that she used to go just to watch the arrival and departure activities in the terminal hall to spot VIPs. Her husband sometimes went to the bar 71 on the ground floor of the building where they lived, to talk with or listen to the pilots and other airport staff who used to go there after work. Tempelhof Central Airport - as long as it was the only airport in West Berlin connected the city to the world. It created a certain feeling of importance and status, and local people living next door to the airport, by using the facilities the airport offered, by watching the daily airport operation or by attending special events, participated in and identified with this importance. Tempelhof Central Airport became part of their local identity. Even though the importance of Tempelhof Central Airport for the air traffic of Berlin has diminished, it is still present in the memories of local residents connected through the feelings they had when it was in its prime and served as “gateway to the world from the 1950s until the 1970s.” The research through interviews clearly showed that this perception of the airport as part of everyday life combines the tangible aspects of the airport building with the intangible aspects of the memory of TCA II in a more balanced and holistic way, than the memory of dramatic events does. 7 Summary and conclusions 7.1 Summary The definition of the multifaceted heritage of Tempelhof Central Airport requires a holistic approach taking into account the history of the location Tempelhofer Feld and of the first airport TCA I, the planning and building process, architecture and construction, function and use of TCA II, the events that occurred on site and the perception of local people as contemporary witnesses as far back as their memory goes. In consideration of the definition of cultural heritage from the World Heritage Convention the heritage related values have been analysed with respect to their tangible and intangible aspects. The result is that the majority of the values are defined by a combination of tangible and intangible aspects which cannot be fully separated. For the estimation of the heritage value of a site, knowledge of both tangible and intangible aspects is essential. Knowledge about the history and circumstances of the site will be made more tangible once it is properly and rigorously documented. This documentary report of the intangible aspects can be 72 passed on to following generations, making the purely “intangible” into a more mixed and more “tangible” aspect. The following facets of Tempelhof Central Airport compose the heritage of the site: History of aviation The area of Tempelhofer Feld is strongly connected to the beginnings of aviation in Europe. It was the stage for flight experiments, spectacular crashes, flight competitions, and Zeppelin airships; it was an arena for German and international flight pioneers, attended by hundreds of thousands of spectators. Urban planning in Weimar times In the context of the urban development of “Groß Berlin” and its transportation system the history of the planning and implementation of the inner city airport of Tempelhofer Feld TCA I is an example of the innovative and farsighted urban planning measures provided by the Weimar government and put into practice by the municipality of Berlin. History of airport design/architecture TCA I was an airport of the generation of first terminal buildings. TCA II is an example of the following generation of airports with a functional concept characterised by vertical separation of visitor- and passenger flows, the linkage of different transportation systems and “dry boarding”. For the lay out of the airfield TCA II is an example for an intermediate solution with concrete aprons and taxi ways bordering an oval airfield with grass runways. Dimensions and size, building materials and building techniques in combination with functional concept were state of the art of the time. Development of the use of green space In the context of traditions of public use of green space and the development of planning and implementation of urban parks in Berlin the area of Tempelhofer Feld is one example with a long and variable history. Example for the Nazi’s use of architecture The building complex was designed as part of the Nazi government’s capital Germania to be the most spacious and beautiful airport in the world as a demonstration for Nazi superiority. The airport building appears to be a unique example for the use of two different styles according to function in one building: 73 monumental classical style for the representative town facing façade in combination with industrial style for the airfield facing façade. History of the Airlift Tempelhof Central Airport became the main setting for a spectacular event of the post-war era. The Airlift was – apart from the practical purpose to guarantee the survival of the West Berlin population – a demonstration of power of the Allied Forces. Therefore the character of the heritage connected to this historical phase is twofold: a demonstration of the Allies’ power and a symbol for friendship and cooperation between the besieged population of West Berlin and their former occupiers. History of the Cold War For the first three decades of the Cold War Tempelhof Central Airport was the main airport of West Berlin and the gate to freedom for refugees from the Eastern bloc states. Location for special events The area of Tempelhofer Feld and later the airfield of Tempelhof Central Airport provided a stage for all kinds of special events: military parades, flight shows, political demonstrations, open house events and even the Red Bull Air Race of 2006. 7.2 Conclusions The impressive architecture of Sagabiel’s building complex, embedded in the urban context, reinforced by the many important historical events that have taken place at the site, mean that Tempelhof Central Airport can be considered as an important heritage site of the 20th Century. A survey of local people who had witnessed the construction and evolution of the current airport, clearly showed that the architectural values make the most important contribution to their perception of heritage. The building and not the associated events dominated the respondents’ perception of Tempelhof Central Airport. As these values are tangible and the building is already protected by legislation, it will most probably survive and the values will be preserved. 74 However, the architecture – in this case the visible elements of the building as they are perceived - is only one part of a more complex heritage which will be incomplete without knowledge about the historical context of the site and the circumstances of its building process and subsequent use. The strongest element of the intangible heritage reported in the interviews was, unexpectedly, the role of the airport in the everyday life of nearby residents. Despite noise and other pollution, the overall perceptions of the airport were neutral or positive. The preservation of Tempelhof Central Airport as heritage is not only the maintenance of the building in its tangible aspects but as well the collection and documentation of the intangible aspects. This thesis aims to contribute to this process of recording the intangible aspects. The main conclusion of this thesis - underlined by the findings of the questionnaire – is, that the intangible aspects of the heritage of Tempelhof Central Airport require greater attention than the tangible ones if they are not to be lost. If this is also the case with other heritage sites, it would suggest the need for continued careful attention to the relative effort being made to preserve the different aspects of heritage. In the specific case of TCA II, the experience of historical events and of the everyday routine connected to the airport is to be found not only in contemporary sources but also in the memories of local residents and other witnesses who are now reaching the end of their lives. These memories are a particularly valuable source which will not be available in the future. It is therefore important to act now collect and document this intangible knowledge to transfer it into a more tangible form. 75 Annex A: Development of air traffic in West Berlin Development of air traffic in Berlin (Conin 1974, p. 350-351) Data until 1959 for TCA only, from 1960 on together with Tegel year passengers 1923 1924 1925 1926 1927 1928 1929 1930 1931 1932 1933 1934 1935 1936 1937 1938 1939 1940 1941 1942 1943 1944 1945 1948 1949 1950 1951 1952 1953 1954 1955 1956 1957 1958 1959 1960 1961 1962 1963 1964 1965 1966 1967 1968 1969 1970 1971 1972 1973 150 1.706 20.428 32.757 40.302 41.214 42.440 48.731 48.448 53.612 81.335 122.814 173.587 216.673 217.368 247.453 154.675 96.343 take offs/landings freight in t 100 20 952 400 9.484 500 12.090 900 16.925 20.799 21.658 29.986 1.200 28.837 32.506 40.202 59.198 2.300 61.369 3.400 60.311 4.600 56.266 5.300 63.571 7.700 42.407 3.200 16.762 3.200 97.046 80.000 20.557 20.000 3.500 300 21.556 41.253 110.886 320.176 483.315 833.718 671.680 834.349 979.945 1.002.510 1.127.235 1.264.809 1.532.035 1.593.887 1.957.491 2.395.640 2.718.189 3.158.914 3.351.969 3.554.192 4.128.743 4.921.814 5.549.298 6.121.406 5.521.803 4.778.411 1.098 2.340 3.943 17.624 25.982 42.791 29.840 28.859 30.492 29.613 30.163 32.081 36.354 40.561 42.068 52.106 63.755 71.009 71.475 72.237 72.903 73.703 78.417 89.625 84.794 76.753 3.200 500 3.700 21.300 33.200 53.600 41.800 36.600 29.200 20.500 11.000 12.600 14.000 16.700 17.400 18.400 19.500 22.500 25.300 27.400 29.700 33.200 37.300 36.500 33.000 30.700 76 77 Annex B: Questionnaires 78 79 80 81 82 83 Fragebogen 7 Masterarbeit: Ein facettenreiches Denkmal - das vielschichtige Erbe des Zentralflughafens Tempelhof Fragen Antworten Name Barbara Wang Geburtsjahr 1941 Seit wann in Neutempelhof 1972 Anmerkungen Verbindung mit Flughafen Nutzer ja Anwohner ja Erste Erinnerung an Flughafen ca. wann, in welchem Alter 70ziger in welchem Zusammenhang abholen des Ehemanns, musste nach Westdeutschland fliegen kaum konkrete Erinnerungen, Procedere mit Pass für Ehemann Eindrücke/Gefühle umständlich Ehemann Chinese, Reise mit der Bahn durch DDR zu umständlich Weitere Begegnungen mit dem Flughafen Fluggast ja ja, zum Abholen und mit Sohn und Mann zum Beobachten des Besucher Flugbetriebes Zuschauer von der Wohnung aus bei Gedenkveranstaltung zur welche Veranstaltungen Luftbrücke Wohnung hat Fenster und Balkon zum Eingangsbereich des Flughafens andere Einstellung zum Flughafen flugbegeistert ja, aber auch umweltbewusst, keine innerdeutschen Flüge technikbegeistert lärmgeschädigt nicht betroffen, aber Verständnis für betroffene Anwohner indifferent andere Änderung der Einstellung? wenn ja, warum? welcher Eindruck steht im Vordergrund Wahrnehmung des Flughafens Nazi-Gebäude Gebäude wird auch damit in Verbindung gebracht Bauzeit ist B. bekannt, sieht Ähnlichkeiten mit anderen Bauten aus der gleichen Zeit Luftbrückengebäude Technikdenkmal Architekturdenkmal Gebäude wird in erster Linie als Architekturdenkmal gesehen Verkehrsgebäude andere Flughafen als Erbe?
