1. THE KNAVE. The site is a blunt headland about 2-5 km S.E. of Rhosili, with a sheer cliff 60 m high on the S., and more broken cliffs on the S.W. and S.E. It has a very wide base in relation to its length, so that although the inner defended area of about o-i ha is only about 45 m by 30 m, the outer defences are 130 m long.
The defences form two more or less concentric arcs:
The site was excavated by Audrey Williams (Mrs. W. F. Grimes) in 1938. The inner rampart was shown to be 4-9 m wide, revetted internally (and perhaps also externally) with at least two courses of limestone blocks. The ditch was 4-3 m wide and I-I m deep, with very gently sloping sides and a slight counterscarp bank. The bank near the cliff on the W. was only 3-7 m wide with no ditch, but with a substantial outer revetment, to accommodate which the rock had been scarped. The entrance was approached obliquely along a ridge of outcrop. On the S. it was protected by a natural scarp with no additions. The bank and ditch terminated on the N., the bank being slightly inturned. No post-holes for the gate were found.
The outer rampart was shown to be 3 to 4 m wide, with an inner kerb of boulders; the ditch was 3-7 to 4-3 m wide and 1-4111 deep, of blunt V-section. At the entrance, the roadway was 3 m wide between the squared ends of the rampart; a line of three post-holes across the middle of the gap indicated a pair of gates closing on a central upright.
Within the enclosure, an occupation layer was found within the inturn of the rampart at the entrance; all the pottery came from this. A natural hollow near the cliff edge on the S. had a hearth and a central post-hole suggesting a round hut 3-7 m in diameter. Small finds from various parts of the site included slingstones, pot-boilers, hammer-stones, part of a stone mace, pieces of clay daub, and sixteen sherds of Early Iron Age B pottery of Glastonbury type dated to the period 50 B.c - A.D. 50.
