Summary

This fort is situated on an irregular rocky ridge that forms the summit of a low hill ESE of Clarilaw. The ground falls away steeply around the flanks of the ridge, particularly on the SE, where a rib of outcrop up to 4.5m thick by 1.2m high serves for the rampart, in the opinion of the RCAHMS investigators in 1949, dressed for the purpose, but elsewhere the defences have been heavily reduced by cultivation and quarrying. As described in 1949, a single rampart was drawn across the SW end of the ridge, while at the NE end two were set likewise some 50m apart, and there was little trace of the inner extending along the NW flank. The first edition of the OS 25-inch map, however, shows no fewer than three ramparts at the SW end, the medial one of which is clearly visible on aerial photographs, despite the gorse growing on the spine of the ridge here. The wide spacing of the ramparts at the NE end suggests there may be two phases of enclosure here, the smaller measuring about 80m from NE to SW by 28m transversely (0.2ha), and the larger rather longer at some 135m in length (0.33ha). Only one entrance is visible and this is at the S end, but others may have been obliterated by cultivation. The interior is featureless.
