Area of archaeological activity found during building work for extension of St. Mary's Primary School. The evidence is part of a larger archaeological complex the extent of which is unknown. Of uncertain date are the ditch (TR 34 SW 657) running across the site, approx. NW - SE, undated although earlier than late 13th early 14th century from finds in a pit that cuts it, and two terraces (TR 34 SW 658) which are likely to be contemporary with the ditch but could be of either Prehistoric or Medieval date. More definite evidence of Medieval date comes from four pits found in the area. They are all of a similar form and are found on both sides of the ditch. The pits contain a mixture of pottery fragments, bones (animal and fish), oyster and other shell fish, stone (worked and rubble) and slag. The Medieval occupation seems to coincide with the main construction periods of the castle. Once the area became abandoned throughout the late Medieval and most of the post-medieval period the site was covered by a thick layer of hill-wash.
