Cairn — unclassified in Bunnamohaun

Situated on a local eminence towards the south-western end of the summit ridge of Knockmore (known locally as ‘the Big Hill’). Although overlooked to NW by the highest point of the mountain (462m), the cairn itself is visible from many points on the island and beyond. As presently constituted, it consists of a low, circular, ancient cairn upon which sits a relatively modern conical cairn. The earlier cairn, roughly circular in plan (NE–SW c. 12.2m, NW–SE c. 11.6m), is flat-topped in profile and is defined by a scarp. Its edges are well defined from N through E and S to SW and are up to 0.65m in height at E. It is composed of compacted angular lichen-covered stone (max. dim. 0.6m). From SW to N, its edges are less distinct and the cairn material is looser, probably as a result of it being partially disturbed and/or robbed out. Traces of shallow pitting in the cairn surface in this sector appear to confirm that it was robbed—probably to build/repair the modern cairn that crowns it. The modern cairn sits centrally on the ancient one. Although placed elsewhere by Ó Muraíle (1999, no. 64, 109), the label ‘Mackenzies Monument’ almost certainly applies to this cairn and suggests that its construction was related to the maritime cartographic work of Murdoch Mackenzie (1774). Of drystone construction, it is a substantial structure, 2.8m in height above the top of the older cairn. It is roughly circular in plan (NE–SW c. 4.3m, NW–SE c. 3.5m), save for a ragged projection at its base in NE sector, possibly the by-product of relatively recent rebuilding. Conical in profile, it is built of angular stones (max. dim. 0.65m) with a rough facing. While the lower courses comprise flat slabs, in general laid horizontally, the upper portions are simply a jumble of stones and slabs wedged into place.
