Evaluation by E Wragg of PCA prior to development revealed a sequence of mid 17th and 18th century layers and pits, associated with domestic and possibly small-scale industrial activities. Sealed by these deposits was an apparent 13th century horizon of mixed redeposited natural sand and silt. No features were observed in this layer, although only a small area could be examined in the confines of the evaluation trench. Subsequent excavations by H Clough of PCA revealed a large, hitherto unsuspected Medieval water feature, which greatly exceeded the extent of the excavation area.
Watching brief by R Ellaby of SyAS during alterations within the grounds, including the excavation of a swimming pool. No features of archaeological interest were revealed, although a few sherds of possible 17th century pottery were noted.
Watching brief by N Shaikhley of SCAU and members of the WCMS on a network of caves identified on the site during work last year. The caves are believed to have been created in the 17th or 18th centuries, at a similar time to others present along the High Street and South Street. Their primary function appear to be as a source of high quality sand, although their subsequent uses appear to have been varied, including modification to use as a World War II air raid shelter.
Evaluation and excavation by P Boyer of PCA prior to residential development. Extensive horizontal truncation, probably dating to the establishment of the barracks during World War II, was found across the majority of the site. However, a Roman enclosure dating to the mid/late 1st century AD was revealed, which probably formed part of a wider agricultural landscape. Later 17th and 18th century agricultural features were also identified in the same area, which appeared to have escaped the truncation evident across the rest of the site.
Excavation by E A Crossland for LDLHS around the well revealed no dating evidence, but it is probably 17th century like the cottage.
Site watching by S Nelson for NAS and Bourne Hall Museum recovered 17th to 19th century pottery groups; one in a cesspit made of reused Merton Priory stone included some 200 clay pipes
Excavation and watching brief undertaken by R Brown of OA in advance of the creation of a swimming pool and related amenities revealed mostly modern deposits, but a rectilinear arrangement of postholes may represent the remains of a simple timber building of possible 16th–17th century date. This may have been a temporary storage or lodging structure associated with the construction of the manor-house or the domestic functions of the west wing. A Kelly of OA also undertook some historic building recording work before and during alterations to Sutton Place
Historic building recording by S Lilley of AOC prior to conversion. The structure was recorded and assessed as dating to the mid-17th century, although the presence of a medieval down brace suggests re-use of materials from an earlier structure. Evidence for a substantial fire within the structure at some point in its history was also catalogued.
Watching brief by H Knight of MOLA, forming part of the project ongoing at this site since 2002 (SyAC 90, 91, 94 and 95), examined the western foreshore remodelling near, but not directly adjacent to, the south of Chertsey Bridge. Truncated deposits of 16th–19th century date were noted, but no evidence was revealed of the medieval Chertsey Bridge structure – presumed to have been located very close to the north of the site. No significant finds or features of earlier date were apparent.
Watching brief by K Johnson of CA revealed alluvial silt sealing successive layers of demolition material associated with the dismantling of the abbey. No in-situ structural remains were encountered in an investigation that by design did not proceed through the complete sequence of deposits in some areas. However, a number of noteworthy finds were recorded, including twelve inlaid medieval tiles from the nationally significant Chertsey tilery, and a coin of 1603, which suggests that the demolition process on the site continued for some time following the Dissolution.
