A magnetometer survey by R Davies of ADAS on the site of a new car park revealed two possible linear features of archaeological origin; however, the presence of significant amounts of ferrous material may have masked other archaeological features. A subsequent watching brief by S Dalby and J McNicoll-Norbury of the same unit, revealed the foundations of a 19th century gymnasium known from cartographic evidence but no other finds or features of archaeological interest. The possible linear features noted from the geophysical survey were not identified. Not all the ground reductions were deep enough to impact the archaeological horizon, including those in the location of a previously excavated Bronze Age burial and Second World War air-raid trenches. Those features, should they survive from their initial excavation and subsequent impacts, and any others that might be present, may remain in situ beneath the west side of the car park and therefore some archaeological potential remains in that area.
