The broch known as Dun Colbost, which occupies a flat-topped hillock edged with low cliffs, is enclosed by a substantial outer wall about 2m in thickness, forming a roughly oval enclosure measuring internally about 32m from NNE to SSW by 26m transversely (0.07ha). By and large the wall follows the cliff-edge, but on the W it cuts back across the crest of the hillock, perhaps suggesting in this case that the enclosure is firmly focused on the broch, rather than in this instance it is an outwork rather than a free-standing enclosure. The entrance is on the NW, while the doorway into the broch is on the WSW. Excavations which examined the area between the broch and the outer wall are as yet unpublished.
