A large irregular feature believed to have been a medieval sand pit was uncovered during archaeological investigations at Brett's Sand Pit. Over thirty sherds of 13-14th century pottery were found and it is thought that this feature was a quarry. Three medieval cooking pots were also found in close proximity and some connection between the pots and the quarry seems likely. The quarry may also be associated with parts of two rectangular enclosures previously found to the north east (TQ 94 NW 56).
