The structure is modest even by the standards of ancient Irish field monuments: a circular hut site just 1.6 metres in diameter, its drystone walls long since fallen to their lowest courses, now standing no more than 0.2 metres high and barely half a metre thick. Heather and gorse have moved in around the edges, softening the outline further. Only two larger stones along the south-eastern arc of the perimeter give any real sense of the original form.

Drystone construction, which uses no mortar and relies entirely on the careful stacking and fitting of stone, was common throughout prehistoric and early medieval Ireland, and hut sites of this kind appear across upland and coastal landscapes where timber was scarce. The outcropping rock and shallow peat at Dunlough suggest a marginal environment, the kind of place where a herder or seasonal worker might have sheltered rather than settled permanently. The internal diameter of 1.6 metres is quite small, closer to a temporary refuge than a family dwelling, though without excavation it is difficult to assign the structure a precise date or function. What survives is the lower skeleton of something once functional, now absorbed almost entirely into the hill.
