Summary

What may be a fort is situated on a cliff-girt promontory on the coast at Aithsetter, which is also occupied by a broch. The defences of the possible fort comprise the remains of two ramparts with a broad medial ditch drawn across the neck to bar the approach from the SW, cutting off an area on the top of the promontory measuring about 65m from NE to SW by 50m transversely (0.3ha). The defences have been heavily quarried, though the ramparts still stand 1.5m above the bottom of the ditch on the S margin of the promontory, and the broch itself has been reduced largely to a mound of rubble about 2.5m in height. According to the Scheduling document, at least three sub-circular hollows that can be seen on the S side of the broch mound may be the remains of structures, one of them with three conjoined compartments.
