Watching brief undertaken by T Munnery of SCAU, and involving C Green of QUEST, during the installation of a pipeline, revealed an area of Late Upper Palaeolithic/Early Mesolithic and Late Mesolithic flintworking and the foundations of a Roman building. A subsequent excavation discovered that the Late Upper Palaeolithic/Early Mesolithic material was found to be an in-situ scatter of lithics with an eastern and western boundary and two areas with a low lithic density that could infer the positions of two knappers. The spatial distribution of the area of Late Mesolithic flintwork encountered could not be plotted. Both of these areas are likely to be short-lived episodes of activity involving the retooling of composite implements. Neolithic flintwork and Bronze Age and Iron Age features revealed provide evidence of prehistoric settlement within the area. The remains of the Roman building comprised the flint foundations of a rectilinear structure, with flue tile above it, suggesting an association with a bath-house. A Saxon posthole was also revealed, allowing the inference of an area of occupation associated with the Hawk’s Hill and Watersmeet burial grounds to the south-east.
