Monument record MHG714 - Broch, Achunabust

The remains of a broch surviving as a turf-covered mound 1.3m high which has been extensively quarried so that the broch shape is destroyed. The mural cell with its entrance to the broch interior survives. Immediately to the W of the broch are the footings of a recent rectangular building with an attached enclosure; disturbed ground around the broch may indicate associated outworks.

The much mutilated, grass-covered remains of a broch, measuring overall 30m in diameter and 0.2m high. The actual wall of the broch, fragments of which can be seen in N and S, appears to have been 4-5.m wide and the internal diameter 8-9m. In the SE there is the opening of a chamber measuring 1.4m by 1m. No trace of any outbuildings associated with the broch could be found. The grass-covered footings which can be seen to the S are of two comparatively modern rectangular buildings.
