Observation by R Young of PCA of geotechnical survey, to clarify the level of truncation across the site. The survey suggested minimal truncation between the existing buildings on the site, and the nature of the deposits indicate a complex history of flooding and reworking of deposits by alluvial action. Possible archaeological deposits containing burnt flints and clay were observed in two boreholes.

Geophysical survey carried out by Matthew McMurray as part of a university project, in order to test for the existence of an eastern enclosure to the Caesar’s Camp earthwork, as defined by William Stukeley in 1723. A number of new features were identified, including the remains of a possible banjo enclosure, and kiln site. A possible Roman building was also noted, although this could not be confirmed. The area of the Caesar’s camp Scheduled Monument was re-plotted, and revealed what appeared to be the remains of a circular ditch within the enclosure.

Continuing monitoring work by J Stevenson of SCAU on stripping of the site in advance of mineral extraction revealed a long stretch of ditch. This probably relates to the possible Bronze Age field system previously identified 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.

Excavation by G Hayman of SCAU revealed evidence of Roman ritual activity, including human inhumations and cremations, and an animal burial, and pits and ditches which may belong to later, 4th century, settlement. Interpretation is tentative as work is in progress, and no finds analysis has taken place.

Excavation by J McKinley of WA of a site on the High Street frontage, and of the former British Gas site, both as part of the Central Trading Estate redevelopment. Limited evidence of Bronze Age activity was observed at both sites, including flood defence measures and probable agricultural activity. The major phase of occupation was in the early Romano-British period, where domestic activity, including an in situ tessellated floor surface and associated wall lines indicative of a substantial structure, and small scale industrial activity was concentrated in the area of the High Street site.

Evaluation by J Robertson of SCAU in advance of a proposed new office development. A large degree of disturbance was noted, to some considerable depth. Archaeological features were observed at lower levels, including a brick floor - either a cellar or cess-pit. Safety concerns prohibited further investigation.

Evaluation by J Stevenson of SCAU prior to redevelopment of the site. A single prehistoric feature was revealed, suggestive of tree clearance. A watching brief subsequently conducted on the site by N Shaikhley of SCAU failed to find any additional finds or features of archaeological interest.

Geophysical Survey carried out by Matthew McMurray as part of a university project, in order to locate the Roman building which excavations nearby in 1986 had suggested may be present in the field. Faint traces of stone walls were identified, as well as a possible roundhouse, which may be associated with the building. The survey also revealed a possible field system. Resistivity work is planned for the area in mid – 2001.
