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)
Continuing excavation and fieldwalking by Plateau recovered further finds of worked flint of Lower Palaeolithic, Mesolithic, Neolithic and Bronze Age date, while pottery dating to the Bronze Age, Iron Age, Romano-British, Saxon, medieval and post-medieval periods was also found. A large Neolithic or Bronze Age leaf-shaped arrowhead and a probable Bronze Age pendant were among the finds. Features on the site included a probable late Roman farmstead enclosure, and a Mesolithic tree-throw pit shelter with rubbish pit.
Excavation following an evaluation by J Leary of PCA revealed a Bronze Age pit (and possibly contemporary features), and evidence of the early development of Stanwell in the form of a gully and two pits containing Saxo-Norman pottery, and slightly later field boundaries. These features were overlain by a ploughsoil containing 12th to 14th century pottery and daub, and point to the existence of a building nearby. A well and a series of rubbish pits containing 18th and 19th century pottery, some rare and non-local, were also excavated.
