Fieldwork by PMG Jones located BA pottery eroding from an old quarry face.

Excavation by S Dyer for SAFG in advance of redevelopment on a site adjacent to Petters Sports Field. BA pottery and worked flint and the possible RB road line were located.

Trial trenches by S Dyer for SAFG in advance of redevelopment. J Chapman noted that some post-medieval pottery and possible kiln wasters and fragments of kiln furniture were found.

Excavation by R J Poulton for SCC, Runnymede BC and HBMC on the site of the ovens known from previous excavations, to test the possibility of public display. The ovens were located , more of the ?precinct wall, previously found , was discovered and the Saxo-Norman levels were again located.

Observation of gravel working by S P Dyer for SAFG located 13 wooden piles and possible IA pottery

Excavation by S P Dyer for SAFG in advance of redevelopment revealed a continuation of the multi period site at Petters Sports Field. Prehistoric worked flints, BA pottery, an IA terret (identified by the BM), a few sherds of probable IA pottery and mixed RB pottery were found in a buried river channel. The previously postulated RB road could not be located and the evidence suggested that it had not existed.

Observation of topsoil stripping and gravel extraction by S P Dyer for SCC and Hall Aggregates revealed a buried river channel.

Excavation by P M G Jones for SCAU, Runnymede Borough Council and English Heritage to provide information for management of the monument. Mesolithic worked flints including cores were found. The postulated defences were sectioned and the site was confirmed as a univallate hillfort; a full detailed survey was carried out by RCHM(E). In a small trench in the interior 53 prehistoric features were found, mostly of early to middle Iron Age date, with post-holes indicating three or more building phases.

Observation and excavation by G N Hayman for SCAU and RMC (Hall Aggregates) indicated prehistoric occupation on the edge of the first area of topsoil stripping. Subsequent excavation produced evidence of BA occupation and then an Iron Age/RB site apparently occupied throughout both periods, with mid to late Iron Age domestic features, RB ditches, pits and possible farm buildings of Flavian to 4th century date.

Trial excavations by I Stuart for HBMC in advance of scheduled monument consent on part of the site of the Chertsey Abbey complex. Four trenches were opened, which revealed that the Black Ditch in this area had been backfilled about 30 years ago with redeposited clay, river gravels, building rubble, modern brick and tyre inner tubes.
