3 Introduction Whitelands College, West Hill, Putney, London Borough of Wandsworth An Archaeological Evaluation by Sian Anthony Report 02/74 This report documents the results of an archaeological field evaluation carried out at Whitelands College, West Hill, Putney, London Borough of Wandsworth, (TQ ) (Fig. 1). The work was commissioned by Mr Christian Gattesco, Planning Manager, Crest Nicholson Residential (South) Ltd, Nicholson House, 41 Thames Street, Weybridge, Surrey, KT13 8JG. Archaeological field evaluation is being carried out in advance of planning permission for a residential development on the site of Whitelands College. Although a definitive development scheme has not yet been determined, some existing structures will be maintained and reused, others will be demolished and some new buildings will be constructed. This takes into account the recommendations of the Department of the Environment s Planning Policy Guidance, Archaeology and Planning (PPG ), and the Borough policies on archaeology. The field investigation was carried out to a specification approved by Catherine Cavanagh, Archaeological Adviser, Greater London Archaeology Advisory Service. The fieldwork was undertaken by Sian Anthony and Danielle Colls between the 9th and 16th September 2002 and the site code is WEI02. The archive is presently held at Thames Valley Archaeological Services, Reading and will be deposited at the Museum of London in due course. A desk-top assessment of the site (Bull 2002) concluded that the site lay in an area of low to medium archaeological potential for the prehistoric period and low potential for other periods. There have been no archaeological sites or finds on the site although several prehistoric artefacts are known from locations nearby. Location, topography and geology The site is located to the south west of Wandsworth between the promontory of Wimbledon Common and the valley of the river Wandle. The site slopes steeply down from 33.5m above Ordnance Datum from West Hill on the north-west to the south-east where the elevation is 19.27m AOD. The site has been raised and levelled considerably above the height of Sutherland Grove which runs along the east of the site, which lies at 18m AOD. (Fig. 2). The site also slopes gently down from west to east. The natural topography has been severely altered by landscaping features that cover the entire site; the southern portion currently being used as a sports field has been 1

4 raised and levelled using large dumps of modern rubble. Garden landscaping has resulted in the construction of large banks of ground surrounding this area. The middle and northern portions of the site have been extensively landscaped in the form of small banks of earth and modern building rubble. Underlying geology is London Clay with some Head deposits (BGS 1981), geology noted in trenches consisted of Head deposits, colluvium and clay. Archaeological background Although no archaeological features or finds have been noted for the site, several Palaeolithic, Mesolithic and Neolithic artefacts have been discovered from nearby (Bull 2002). There are only isolated Roman and medieval finds from the vicinity. The area remained undeveloped until into the 18th and 19th centuries. Construction of buildings associated with the Wimbledon Park estate started in the 1700s, and much landscaping occurred towards the end of the 18th century. The hospital to the west of the present site was founded in these buildings in 1854 with the main hospital constructed 10 years later. Whitelands College bought the garden area to the west of the hospital in 1924 with most of the present buildings and chapel being built at this time. Objectives and methodology The purpose of the evaluation was to determine the presence/absence, extent, condition, character, quality and date of any archaeological deposits within the area of development. The trenches were to be excavated with a machine fitted with a toothless ditching bucket under constant archaeological supervision. Trenches were then hand cleaned. All spoilheaps were monitored. All potential archaeological features were hand dug and recorded. Twenty-five trenches were originally proposed, positioned to evaluate the whole site including areas in the north that have previously been developed. However, access to these northern parts of the site was not possible whilst the active use of the college and following consultation with Mr Robert Whytehead of Greater London Archaeological Advisory Service, a number of the trenches were not excavated. A complete list of trenches giving lengths, breadths, depths and a description of sections and geology is given in Appendix 1. Results Trench 1 2

5 The stratigraphy consisted of topsoil of 0.26m overlying a brown, fine-grained clayey silt which was Head deposit (0.1m deep). A test pit was excavated at the southern end to confirm the depth of the natural clay beneath the Head deposits, the natural clay was reached at 17.67m above Ordnance Datum. Trench 2 (Plate 1) The stratigraphy consisted of topsoil (0.15m) overlying a brown silty clay subsoil (0.11m). This was truncated at the south-west end of the trench by a hard-packed chalk layer and dark silty clay of 0.5m depth. To the northeast end of the trench a large layer of redeposited Head or colluvium mixed with brick and tile lay on top of undisturbed Head deposits. Potential archaeological features were hand cleaned and excavated in this trench (Fig. 4). Feature (1) was rectangular in plan, 1.6m long and 0.9m wide with a V-shaped base that was 0.08m deep; the fill was a grey-brown silty sand. Although there was a slightly irregular base, the regular shape indicates it was caused by human activity. Finds of post-medieval pottery, clay pipe stems and tile indicate it to be a postmedieval feature possibly connected with the extensive landscaping done to the site in the 18th and 19th centuries. Feature 2 was a curvilinear feature, 1.9m long, 0.5m wide. When excavated it proved to be shallow (0.12m deep) with a flattish base. Clay pipe stems were also found in the fill which was a dark grey-brown sandy silt; this also is considered to be a post-medieval landscape feature. Trench 3 Extensive tree root action was present in this trench with a modern brick-lined drain aligned south east- north west. Several patches of irregular mixed dark soils were investigated by hand to confirm they were tree holes. Trenches 4 and 5 (Plate 2) These trenches contained large deposits of brick, tile and concrete rubble at their southern ends; there were also two possible layers of Tarmac, these all were up to1.06m deep. These truncated the natural levels of redeposited Head colluvium although not the undisturbed levels of natural Head deposit. Two service pipes and two field drains were evident in Trench 4 but none were present in Trench 5. A further natural feature in the far south of Trench 5 consisted of a thin layer of green-grey clay (0.13m thick). This seemed to be a discrete deposit that continued up to 5m through the trench. It was not observed in any other trench. 3

6 Trenches 6 9 and 12 The stratigraphy consisted of topsoil between 0.19m and 0.35m deep overlying undisturbed sandy clay variations of Head deposits. These were relatively shallow trenches that contained only tree root action that were investigated by hand. There were no colluvial soils and no redeposited head deposits. Trench 10 The stratigraphy consisted of topsoil (0.18m deep) onto a modern rubble and soil mix (0.52m) onto undisturbed Head deposits. Several modern foundation walls were uncovered, two aligned north east- south west and one between these two aligned west- east. All were of modern red brick material 2-3 courses high over a foundation rubble. Modern white-glazed willow pattern pottery was found in the cuts for these walls. A metal box shape was found next to these walls. Only 0.6m square made of lead with large metal rivets, the sheet metal was bent over in one edge to create a box-shape, this was filled with modern rubble, tiles and glass. It is thought that this was remains of part of the drainage system connected with the brick structure. A dump of modern rubble lay at the eastern end of the trench in a square cut, again this was filled with modern rubble, tiles and glass. Trench 11 The stratigraphy consists of 0.33m of topsoil overlying a redeposited Head colluvium mixed with modern brick rubble, onto an undisturbed Head deposit. Substantial modern brick foundation walls and brick drains were found in this trench, all associated with modern porcelain pottery and glass. In the far southern end of the trench the corner of a small red brick structure was uncovered. Running out from underneath these at 19.33m AOD were two brick built drains aligned South west- north east. Towards the middle of the trench were two more substantial brick walls, two brick-lengths wide and going to the level of the natural at 19.33m. The walls were six courses high rising to just below the current ground level of 21.16m AOD. A further large brick wall was encountered at the far northern end of the trench. This was of similar construction as the two larger walls, going to a depth of 20.12m AOD. Finds Three clay pipe stems were found from Features (1 and 2). They were carefully manufactured and bored with a very small hole. A fragment of late post-medieval white glazed pottery rim was found in Feature (1); it comes from a small jar. The finds were not retained 4

7 Conclusion The features excavated in Trench 2 are clearly of a relatively recent (late 18th century or later) date. Their shallowness indicates ephemeral features probably connected with the extensive landscaping associated with the buildings and later hospital to the west of the site. The depth of the features (18.47m AOD compared to the current ground level of 19.27m AOD) shows how much recent landscaping has been applied to the southern portion of the site. The large brick structures are modern, indicated by the bricks and the associated finds. They have potentially destroyed any features that may have occurred in the older ground levels. With only natural features in the rest of the site, it seems that there is no archaeological potential in this part of the site.
