The general topographic location of the PDA and the known archaeology of the area, being located within the area of the Anglo-Saxon and medieval settlement of Sudbury and in particular upon the site of the medieval St Gregory's College, suggests that there is a moderate to very high potential for encountering archaeological remains within the PDA but that such deposits are likely to be affected by the PDA's recent land-use and in variable states of preservation. Further archaeological investigation, beginning with a programme of trial trench evaluation is recommended (S2).
