Summary

This small fortification occupies the SE end of a rocky ridge that rises some 25m above the E shore of Loch nan Gabhar. Dropping precipitously on the NE, SE and SW, the only line of approach from the NW is blocked by a single wall that also extends along the cliff-edge on the NE. The wall itself is heavily denuded, comprising little more than a band of rubble from 1m to 3.3m thick with occasional facing-stones marking the line of the outer face. The rocky and featureless interior measures about 45m in length from NW to SE by no more than 12m in breadth (0.04ha). The entrance is midway along the surviving wall and opens onto a slope above the cliff-edge on the N. Excavations in 1908 by Alan Reid identified a concentration of vitrified stone somewhere at the W end (Reid 1909, 36, fig 3), but RCAHMS investigators found only a single piece in the screes at the foot of the slope on the SW, concluding that Reid had overestimated the length of the fort, and thus placing the site of his discovery some 30m outside the wall. Given the crude rendering of his plan, however, this level of sophisticated interpretation may be misplaced, and it is perhaps more likely that the placing of the cross on his plan bears a local relationship to the W end of the fort, thus placing the vitrifaction that he discovered in the wall at this end.
