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.

Continuing excavation by R Poulton of SCAU revealed further evidence of Roman activity.

Excavation by P Jones of SCAU revealed near shore deposits, incorporating some Roman artefacts, but otherwise no significant archaeological deposits.

An initial evaluation by G Potter of CA revealed archaeology of medieval and post-medieval date. A subsequent watching brief identified similar finds and features from these periods, including the ground plan of a small post-medieval cottage. Although at present only provisional dates are available, several features appear to relate to the Roman period including a significant length of ditch. A single inhumation in a square burial pit was also excavated. The skeleton has been dated to the Iron Age, and belongs to a female in her late 40s.

Watching brief carried out by J Robertson of SCAU during work on drainage trenches and soakaway pits for a new all-weather sports surface. The narrow width of the trenches made it difficult to check for the presence of features, and only a sherd of Roman pottery was recovered from the subsoil of one of the soakaway pits. A number of finds, which included several pieces of struck flint, fragments of burnt flint, a lava quernstone fragment, and medieval or post-medieval tile, were retrieved from the spoil heaps.

Evaluation by S Ford of TVAS prior to residential redevelopment revealed no features of archaeological interest, although a few sherds of residual Roman and medieval pottery were 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)
