Observation by D W Williams of the digging of floodlight cable trenches south of the standing buildings revealed a number of general levels: featureless brown sandy loam below possibly 16th/l7th century layers below a possible 18th century courtyard surface, itself below a spread of late 19th century stone and brick rubble. At three points adjacent to the sunken garden were observed the substantial footings of stone walls bonded with yellow mortar.

Excavation by D W Williams of the surviving north-east corner of a 17th century building reconstructed in the 18th century. A section had been recorded in 1989; it had been discovered when a substantial part of the remains were removed for use as backfill for sand caverns. There was no evidence for earlier occupation along this part of London Road. Finds included part of a 16th century mullion and transom window, possibly from the Priory, and a complete late l7th century wine bottle, still corked and half full. (275)
