An archaeological watching brief was undertaken by Cotswold Archaeology during

groundworks associated with the excavation of 146 postholes for the installation of a fence

1. INTRODUCTION

1.1 In November and December 2018 Cotswold Archaeology (CA) carried out an

archaeological watching brief at the request of Ecovigour Ltd, on behalf of Bristol

City Council, at Purdown Heavy Anti-Aircraft (HAA) Battery, Stoke Park Estate,

Bristol (centred at NGR: 361134 176470, Fig.1).

1.2 In line with the recommendations of a Conservation Management Plan (CMP) for the

site (CA 2015), works were planned to clear the site of scrub, trim the trees, remove

the old fence and install a new fence around the perimeter of the scheduled

monument. As the works have the potential to impact upon archaeological remains

which form a Scheduled Monument (ref. SM BS 184, HA 1004531), consultations

were conducted with Hugh Beamish, Inspector of Ancient Monuments, Historic

England (HE). The required Scheduled Monument Consent (SMC) has been issued

under reference: S00175848.

1.3 The watching brief was carried out in accordance with a detailed Written Scheme of

Investigation (WSI) produced by CA (2018) and approved by Hugh Beamish. The

fieldwork also followed Standard and guidance: Archaeological watching brief (CIfA

2014). It was monitored by Hugh Beamish.

The site

1.4 The Scheduled Monument is approximately 1.1ha in extent and is located at c. 83m

AOD within the boundaries of Stoke Park Estate. It comprises four octagonal gun

positions, two square gun pits, two magazines and a command post. The monument

as a whole is currently largely obscured by scrub, trees and dense undergrowth. The

monument has suffered vandalism, with the old fence partially removed and graffiti

covering the four octagonal gun positions.

1.5 The underlying bedrock geology of the area is mapped as Wilmcote Limestone

Member - Limestone and mudstone, interbedded of the Triassic and Jurassic

periods (BGS 2018). Natural geological substrate consisting of yellow clay and

limestone brash was observed during the watching brief, at an average depth of

0.2m below present ground level (bpgl).

2. ARCHAEOLOGICAL BACKGROUND

2.1 The CMP for the site (CA 2016) fully documents the historic background of the site,

as well as the historic context of national anti-aircraft defence during the Second

World War. The following is a brief background of the Purdown Battery itself.

2.2 The Scheduled Purdown Heavy Anti-Aircraft (HAA) Battery is located within the

Stoke Park Estate, which is a Grade II Registered Park and Garden. The park was

part of a group of large estates owned by the Berkeley family, a prominent noble

family in Bristol. In the 20th century Stoke Park House was bought and expanded to

become an orphanage and mental health hospital. The House and Parkland were

taken over by Stoke Park Group Hospital Management Committee in 1948, and then

transferred to NHS trusts. Purdown HAA Battery became operational as a mobile

anti-aircraft site in November 1939, before being converted to a permanent

reinforced concrete and brick built battery in June 1940. Within the HAA battery was

a command post and other associated buildings such as a canteen and

accommodation. It originally had four octagonal gun emplacements, with two square

gun positions with magazines added later in the war, along with small mobile gun

positions in the wider landscape around the original battery, the latter two groups

distinguished by concrete block construction. The site also had a camp located

adjacent to it. The site of the battery dominates a topographic point along a plateau

edge which has far reaching views of Bristol and was a perfect vantage point for

spotting enemy aircraft. The HAA Battery gained notoriety as ‘Purdown Percy’, with

the noise of the simultaneous firing of the guns echoing around the surrounding

area. Bristol Aeroplane Company at Filton, the Avonmouth Docks and the docks at

Bristol Harbour within the city were the main target for enemy bombs, and so the

HAA Battery on Purdown would have been protecting these targets. The HAA

Battery was decommissioned in mid-1946 (CA 2016, 10).

2.3 Archaeological evaluation was undertaken at Purdown Radio Station, c.50m south-

west of the Scheduled Monument (BaRAS 2001). This evaluation revealed no

archaeological features of significant antiquity within the area of the radio station.

Brick flooring was found in the trenches which is most likely to be associated with

the camp associated with the gun battery (CA 2016, 3).

2.4 A condition survey of the Scheduled Monument (BaRAS 2015) found that many

extant structures within it, were suffering from vandalism, graffiti and damage


5


caused by extensive vegetation growth. Some structures had collapsed and a few

were showing signs of localised cracking, although generally the structures were in

good structural condition (CA 2016, 2).

3. AIMS AND OBJECTIVES

3.1 The objectives of the archaeological works were:

• to monitor groundworks, and to identify, investigate and record all significant buried

archaeological deposits revealed on the site during the course of the development

groundworks;

• at the conclusion of the project, to produce an integrated archive for the project work

and a report setting out the results of the project and the archaeological conclusions

that can be drawn from the recorded data.

4. METHODOLOGY

4.1 The fieldwork followed the methodology set out within the WSI (CA 2018). An

archaeologist was present during intrusive groundworks comprising the excavation

of 146 postholes, measuring approximately 0.3m in diameter, for the installation of a

new fence around the perimeter of the monument (see Fig. 2).

4.2 Where archaeological deposits were encountered written, graphic and photographic

records were compiled in accordance with CA Technical Manual 1: Fieldwork

Recording Manual.

4.3 The archive from the watching brief is currently held by CA at their offices in Kemble

and will be deposited in Bristol’s Museums, Galleries & Archives. 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.

5. RESULTS (FIGS 2-3)

5.1 No features or deposits of archaeological interest were observed during

groundworks and, despite visual scanning of spoil, no artefactual was recovered.


6


The following is a brief summary of the contexts observed. For a more detail

description, and measurements, see Appendix A.

5.2 The natural geological substrate consisting of light yellow clay and limestone brash

was encountered in all excavated postholes between approximately 0.2m to 0.4m

bpgl. Within postholes 4, 5, 14-67, 70-73, 76, 77, 8 and 85, the natural substrate

was overlain by dark grey-brown silt subsoil measuring up to c.0.3m in thickness.

This was in turn covered by topsoil. Within postholes 6-13, 68, 69, 74, 75, 78-83 and

86-146, subsoil was not present and the natural substrate was covered directly by

topsoil.

5.3 Exceptions to the above are postholes 1, 2 and 3, where subsoil was overlain by a

modern gravel makeup deposit, which was in turn covered by tarmac.

6. DISCUSSION

6.1 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. The limited scale of the completed groundworks

precludes any statement on the presence or condition of any of the aforementioned

remains in this location.

7. CA PROJECT TEAM

Fieldwork was undertaken by Monica Fombellida, Mathew Coman and Adam

Howard. The report was written by Sara-Jayne Boughton. The illustrations were

prepared by Rosanna Price. The archive has been compiled and prepared for

deposition by Hazel O’Neill. The project was managed for CA by Richard Young.
