Summary

A broch stands at the landward end of heavily eroded promontory that may once have connected to a precipitous stack that now lies a little over 10m offshore at its seaward end. Thought by Raymond Lamb to be a 'blockhouse' controlling access to the promontory (1980, 79), the character of the broch was proved by excavation in 1981-2 by the late Peter Gelling, though the work was left uncompleted and unpublished, and although there is no evidence of other defences across the neck, traces of settlement structures have been observed around the broch and extending along what is left of the crest of the promontory beyond it; in addition other structures can be seen on the stack, the summit of which measures about 65m from ENE to WSW by 20m transversely (0.11ha). Before the stack was detached, the promontory would have extended to about 0.28ha and would have been ideally suited for an earlier promontory fort, though for the present the case remains unproven.
