Summary

The broch that stands on the E bank of the Black Water, occupying the crest of a precipitous hillock which drops away sharply to the river along its SW flank, is also enclosed by the remains of walls that are usually regarded as outworks. Indeed the outer wall on the SE appears to abut the broch wall on the E, though in the opinion of the John MacRae, the OS surveyor who visited in 1976, this sector has been rebuilt. Elsewhere, it is reduced to no more than a band of rubble extending along the lip of the summit, not only forming an outer enclosure in front of the broch entrance on the SE, but also around the less obviously accessible area to its rear on the NW. While it may be a contemporary outwork, it is equally possible that these are the remains of an earlier enclosure on the hillock measuring about 45m from NW to SE by up to 15m transversely (0.05ha). The broch itself still stands 3m high in places and displays several architectural features, including the checked and roofed entrance passage, bar-holes, a guard chamber, aumbries in the inner wall-face and mural galleries. A wall extending around the foot of the hillock on the NE is probably a later stock boundary.
