In a trench cut across the lawn at the southern end of South Close a short stretch of chalk, flint and Caen rubble wall, associated with a burnt clay and mortar floor was found although much of the area had been truncated by an 18th or 19th century basement. The exposed face of the wall was extensively fire-reddened and crushed mortar and chalk rubble filled the room up to the cellar truncation. The wall ram almost exactly perpendicular to the interpolated line of the early precinct wall and was probably early medieval in date. Although there is no firm date for the wall, there was a fire in 1174, but equally the damage could have been caused by a hearth being positioned here
