INTRODUCTION
1.1
In October 2012 Cotswold Archaeology (CA) carried out an archaeological watching
brief for Mr P Collins at Pen-y-Bryn (centred on NGR: SO 8498 0316; Fig. 1). The
watching brief was undertaken to fulfil a condition attached to planning consent for a
two storey extension to the existing property (Planning ref: S11/969/HHOLD). The
objective of the watching brief was to record all archaeological remains exposed
during the development.
1.2
The watching brief was recommended by Charles Parry, Senior Archaeological
Officer, Gloucestershire County Council (GCC), archaeological advisor to Stroud
District Council, and carried out in accordance with a subsequent detailed Written
Scheme of Investigation (WSI) produced by CA (2012) and approved by the SDC
acting on the advice of Mr Parry. The fieldwork also followed the Standard and
Guidance for an archaeological watching brief (IfA 2008), the Statement of Standards
and Practices Appropriate for Archaeological Fieldwork in Gloucestershire (GCC
1996), the Management of Archaeological Projects 2 (English Heritage 1991), and
the Management of Research Projects in the Historic Environment (MORPHE):
Project Manager’s Guide (EH 2006).
The site
1.3
The site is 0.25 hectares and is bounded to the east and west by residential
properties and gardens, to the south by a residential road, and to the north by
Rodborough Common (Fig. 2). It lies on a promontory between the Stroud and
Nailsworth valleys at approximately 180m AOD. The underlying geology of the area
is mapped as Salperton Limestone Formation of the Jurassic Era (BGS 2012). The
geology encountered comprised limestone in a yellow silty sand matrix overlying
limestone brash.
Archaeological background
1.4
The development area lies between Rodborough Common to the north and
Minchinhampton Common to the south. Both areas have recently been subject to
surveys conducted by Gloucestershire County Council Archaeology Service.
Rodborough Common was found to contain 187 sites and monuments dating from
3

the Bronze Age to the present (Parry 1993, 233). The survey of Minchinhampton
Common identified approximately 300 sites ranging in date from Neolithic to Second
World War (Russet 1991, 237).
1.5
The development area lies at the southern, visible, limit of an extant earthwork that
is aligned north to south and comprises a bank with a ditch to the east. The extant
earthwork extends for approximately 90m, although until the 1950s it could be traced
for an additional 80m southwards (Parry 1996; see Fig. 2 for location and former
extent). The earthwork, and the area immediately to the east, was archaeologically
investigated between 1936 and 1955; these works have more recently been
reviewed by Parry (1996) and can be summarised as follows.
1.6
A trench was excavated across the northern extent of the earthwork by Clifford
(1937), with sherds of early Roman pottery, as well as abraded fragments of late
Iron Age pottery, being recovered from the bank. This earthwork, and those at The
Bulwarks, Minchinhampton and Amberley Camp, were interpreted as the boundaries
of a Belgic oppidum (Clifford 1937, 300).
The earthwork was subsequently
reinterpreted as the defences of an early Roman military camp by B. and H. O’Neil
(1952, 26-7). This interpretation was based on possible banks visible on the ground
surface and aerial photographic evidence showing a rectilinear cropmark, enclosing
an area of 3.24ha, to the east of the extant earthwork. Evidence of late Iron Age and
early Romano-British activity was identified by Clifford (1964, 145) within a
foundation trench.
1.7
The two ditches identified from aerial photographs by B. and H. O’Neil were
excavated in advance of residential development (Rennie 1959). The earliest ditch
was dated to the 1st century A.D. Although no finds were recovered from the later
ditch a medieval date was suggested for it. Together with the extant earthwork, this
later ditch was considered to comprise a medieval agricultural enclosure located on
an area of earlier occupation, with the Roman finds recovered from the bank in 1937
being residual in character. Using documentary and aerial photograph evidence,
Parry argued that the later ditch is unrelated to the extant earthwork.
He also
suggested that the cropmarks and extant earthwork enclose an area of 9.80ha and
functioned as the boundary of medieval agricultural enclosure (Parry 1996, 155).

Methodology
1.8
The fieldwork followed the methodology set out within the WSI (CA 2012). An
archaeologist was present during intrusive groundworks comprising the excavation
of the foundation trench for the extension to the existing dwelling (Fig. 2).
1.9
Where archaeological deposits were encountered written, graphic and photographic
records were compiled in accordance with CA Technical Manual 1: Fieldwork
Recording Manual (2007).
1.10
The archive from the evaluation is currently held by CA at their offices in Kemble.
Subject to the agreement of the legal landowner the site archive will be deposited
with Museum in the Park, Stroud. A summary of information from this project, set out
within Appendix B, will be entered onto the OASIS online database of archaeological
projects in Britain.
2.
RESULTS (FIG 2)
2.1
Natural limestone brash 105 was revealed at an average depth of 0.9m below
present ground level and was sealed by loose limestone in a yellow silty-sand
matrix, 104. This was overlain by 0.26m of subsoil, 103, which was in turn sealed by
0.12m of buried topsoil, 102. This was covered by 0.2m of modern levelling deposit
101 for the existing gravel surface, 100.
2.2
No features or deposits of archaeological interest were observed during
groundworks and, despite visual scanning of spoil, no artefactual material pre-dating
the modern period was recovered.
3.
DISCUSSION
3.1
Despite the archaeological potential of the application area (see archaeological
background above), the watching brief identified no archaeological remains within
the area of observed groundworks. This absence of archaeological deposits
suggests that features and deposits associated with the earthwork and adjacent
ditches do not extend as far west as the current development, or that they may have

been truncated during previous groundworks associated with the construction of the
existing dwelling.

CA PROJECT TEAM
Fieldwork was undertaken by Rebecca Riley. The report was written by Rebecca
Riley and the illustrations were prepared by Lorna Gray. The archive has been
compiled by Rebecca Riley, and prepared for deposition by James Johnson. The
project was managed for CA by Cliff Bateman.
