A geophysical survey of the area surrounding the souterrain, commissioned by the Council, reported, "... an unusually large number of archaeological features including....a large enclosure complex, or a series of succeeding complexes, to the western side of the survey area appearing to be associated with at least one substantial stone structure, of medieval or post-medieval origin. In the north, the souterrain appears to dominate the landscape with all adjacent archaeological features respecting its limits, with the added possibility of a trackway leading to it. In the east another potential enclosure was identified."
