Occupying a rocky knoll above a precipitous crag that falls away abruptly into the valley of the River Oich on the E, this small fortification displays three roughly concentric lines of defence. The inner encloses the very summit of the knoll and measures 19m from NNE to SSW by about 10m transversely (0.02ha) within a heavily-vitrified wall reduced to a mound of rubble in excess of 3.5m in thickness where it is best preserved on the N and W flanks. The entrance is not visible, though probably on the SW and the only feature that can be seen within the heavily overgrown interior is an old excavation trench transecting the northern end. The second line of defence is a wall that extends around the shoulder of the summit area to enclose a larger area measuring about 38m along the same axis by a maximum of 18m transversely (0.06ha). Though reduced to a scarp everywhere except the N, in 1974 the OS surveyors were still able to trace the line of the outer face discontinuously round the whole circuit, but the only vitrified stones visible appeared to have tumbled from the innermost wall above. The entrance is on the SW, where a gully drops down the slope to the rear of the third line, yet another wall, extending around the foot of the knoll on the NW and S. Again, the OS observed a run of the inner face and a few outer facing-stones on the NW; here this third wall is about 1.7m in thickness, possibly increasing to about 3m adjacent to the entrance on the S. The sequence of construction is uncertain, though on the grounds that the middle wall seemed to be more heavily reduced than the inner, and that none of the pieces of vitrified stone they found on the lower walls appeared to be in situ, the OS were of the opinion that the inner enclosure on the summit had been inserted into an earlier fort.
