A watching brief was maintained by J Robertson of SCAU, for RMC Aggregates (UK) Ltd, on soil stripping in advance of mineral extraction. The site revealed no features of archaeological interest, although stray finds recovered include two struck flints and a sherd of Saxon grass-tempered pottery. Fragments of burnt flint and pieces of medieval and post-medieval tile were observed over much of the stripped area.
Evaluation by D Dobson and D Killock of PCA, for Crest Homes, revealed evidence dating from the post-medieval period to the present day. One trench produced Bronze Age flintwork and a late 12th century pit. Further work revealed a truncated ditch aligned roughly east to west, the fills of which contained a sherd of Mid-Late Saxon pottery and one dating to the 12th century. This feature is likely to be the remains of a field or enclosure boundary.
Evaluation and excavation by S Weaver and J Saunders of TVAS, for HBG Properties, of a site to be redeveloped for warehousing, did not reveal evidence for the barrows mentioned in this vicinity in the Merstham boundary charter of 947 AD. The evaluation did reveal a number of dateable pits and ditches indicating the presence of a late Iron Age / early Roman settlement. One of the features was initially thought to represent part of a curvilinear boundary ditch, but the subsequent excavation illustrated that this was one of two rectilinear ditches on the site.
Evaluation by J Pine of TVAS in advance of redevelopment revealed a concentration of features in one part of the site. The features comprised pits, postholes and two possible ditches, and may represent several phases of activity. The features that could be dated appear to be from the early Medieval period, but the discovery of pottery of Roman and early to middle Saxon date suggests activity of those dates in the near vicinity. Excavation of this area is proposed for the future.
Watching brief by K Sabel of PCA on geotechnical trial pits. Evidence for the 17th-18th century origins of the building were revealed, including earlier foundations, drainage and timber flooring. Remains pre-dating Waterloo House were also revealed, in the form of surviving post-medieval layers and residual medieval building material. Considerable evidence of Saxon/Early Medieval occupation was recovered also.
Continuing monitoring work by J Stevenson of SCAU in an area located immediately to the south of previous work undertaken in 1999 and 2000. The more securely dated features include: a Neolithic pit containing a complete Ebbsfleet bowl; several mid--Late Bronze Age pits; a small Iron Age pit containing nothing but a complete triangular loomweight; three sides of an enclosure of prehistoric date; the right-angled corner of a Roman enclosure, leading towards an area of concentrated Roman activity identified previously, and some middle Saxon pits.
Evaluation and subsequent excavation by T Carew of PCA in advance of the construction of a new prison. A palaeochannel, probably dating to the late glacial to early post-glacial period, cut through the centre of the excavated area. A probable early Mesolithic flint blade was recovered from near the channel, although it was found in a later context. The earliest of the cut features was a pit with a probable placed deposit of early Neolithic flintwork. This was adjacent to a middle to Late Neolithic ring ditch, interpreted as either a hengiform monument or a barrow.
Excavation by C Challis and S Coles of TVAS following an evaluation of the site in 2000. The excavations took place on the west bank of the river Wraysbury in an area thought to have been an island in times of flood, and exposed features comprising pits, postholes, ditches and a possible enclosed area. Features can be provisionally dated to the early medieval period (11th--12th century), but pottery of Roman and early to middle Saxon date was also recovered.
Evaluation, excavation and watching brief by D Palmer of AOC, as part of the ongoing revitalization project. Two large sites were investigated, to the west and east of Guildford Road, just to the north of Chertsey Station (phases 7 and 8 respectively).
Watching brief and subsequent excavation by J Robertson of SCAU of an Early Bronze Age ring ditch, probably originally surrounding a barrow. Two inhumations were found at the base of the ditch, and Neolithic flintwork, Roman ditches, and Saxon pits were also discovered. (355)
