 In order to accommodate a concrete support base for the proposed display cabinet that is to hold the Stepney armorial dinner service, a large trench had to be excavated in the centre of the room, which offered archaeology the opportunity to evaluate the floor deposits below the 17th-century floor level more thoroughly than was possible for the already re-opened trial pit in this room.Excavations for this trench revealed that approximately 0.35 m below the 17th-century floor was an earlier floor level of compacted orange/buff coloured clay.This surface had been covered over with a loose demolition deposit of soil/sand, lime mortar and wall plaster, which in turn had been compacted with earth.
