Emergency excavations were carried out for the Ministry of Public Buildings and Works, during October and November 1963. This important site has for many years suffered from the attentions of untrained amateurs, whose diggings have done a considerable amount of damage. The added threat of building operations connected with the new power station occasioned the present excavations. Site 4 (field 6), a mound with a possible building beneath it. (1) Site 4 remains undisturbed (other areas now destroyed). Trial trenches. Neither plans nor finds from this site are available now. (2) See E124 for nearby excavation by Houldsworth, E125, E128 and E699 for Greenfield sites 1-3.
