Examination of the cellars by GMVEU led to the discovery of an infilled chamber which, when excavated, was found to be a small room built of dressed chalk of which a little over a metre in height survived above floor level. The remains of what appeared to be blind arcading above a ledge survived, with doorways at the north west and south east corners of the chamber. Stylistically the room appears late 12th century in date. The rubble infilling the room contained material no earlier than the 1270s. (300)
