Excavation of part of the earthwork known as Little Pickle by R J Poulton for SCC and British Industrial Sand Ltd, in advance of sand extraction, revealed that the bank and ditch of this rectangular earthwork were probably constructed in the late 15th century. Large quantities of roof tile from trenches within the earthwork suggest the presence of buildings there. Outside the earthwork, some 50m to the south, building foundations were discovered. The large amount of building debris from the final fill of the ditch of the earthwork probably came from the demolition of this building, probably in the 16th century. (189)
