Several anomalies were observed during a geophysical survey undertaken at three locations within the grounds of Dover College, Effingham Crescent. It is likely that many of these relate to walls and buildings which once formed part of the medieval priory (St Martins Priory) though this has not been confirmed archaeologically. The features which are most likely to have a medieval date were located in areas 1 in the north western corner of the complex, and area 2 in the south west corner of the complex, close to the gatehouse. In area 1 a range of features were identified which appear to be at a depth of between 15cm and 85cm below the ground level. The northern most appears to be a substantial foundation, with an apsidal end at the east. The sections are fragmentary, suggesting robbing after demolition. These sections line up with the north side of the medieval building to the east. To the south of these and parallel to them are further anomalies again possibly representing foundations, but they are more fragmentary (perhaps suggesting more substantial robbing). Between these tow sets of anomalies was a third set of short linear features, these could be a utility but their position exactly between the others and their fragmentary nature suggest they are related. In area 2 two groups of features have a possible Medieval date. The first is towards the northern end of the surveyed area and appears to be a substantial set of foundations at a depth of 15cm to 50cm. They are on a different alignment to the adjacent building to the south, but are on the same alignment as the medieval chapel to the north, suggesting a similar date to that. The second is towards the southern end and again appears to be a very substantial wall foundation, at a depth of 50cm to at least the surveyed depth of 160cm. It is somewhat disturbed at its top end by the building on the western side of the survey area, but its course is clearly visible. It is aligned to the southern edge of the medieval gatehouse, so it is very likely that this is a boundary wall associated with the gatehouse. (1)
