Activity on this site commenced with the digging of robber trenches in the late 11th or more likely the 12th century. These trenches, and the site as a whole, produced quite a high concentration of late Saxon Thetford-type ware but all of this seems to have been residual. An episode of pit-digging succeeded the trenches, probably in the 13th century. The pits were probably cess-pits relating to buildings on the street frontage. One of these pits produced Stratified Group 7. <1>
