Summary

This fort occupies a precipitous promontory on the NW coast of the island of Unst, running out between two deep geos which have bitten back into the neck to leave little more than a narrow ridge linking to the cliff-line on the ESE. The defences comprise a single wall drawn across the rising ground on the seaward side of the neck, immediately behind which there has evidently been a stone structure, its walls now reduced to grass-grown mounds of rubble. The promontory is actively eroding, and its flat summit is now a maximum of 25m broad and tapers WNW to a narrow spit some 70m beyond the wall; formerly it was almost certainly much larger, and it was probably possible to descend the outcrops beyond this point virtually to sea level. Apart from the stone structure immediately to the rear of the wall, the low footings of two oval or sub-rectangular buildings can be seen towards the WNW end of the summit, where Raymond Lamb also identified a roughly square hollow in its surface (Lamb 1980, 36 fig 13, 86).

Investigation History

There is no reason to believe that this promontory was ever the site of a broch, the appellation of 'brough' on the ist OS map merely signifying a place believed to be of antiquity
