It is a modest thing by any measure, roughly 3.5 metres by 3.2 metres across and less than a metre high, its walls about a metre thick, built in the drystone fashion where stones are stacked without mortar and rely on their own weight and careful arrangement to hold. What gives the site a quiet particularity is that field clearance, the stones gathered from working the surrounding land, has been piled up against the outside of the walls. The labour of clearing ground and the labour of building shelter have collapsed into the same small structure.

Locally, the place is known as 'an liosachán', a diminutive form suggesting something in the nature of a small enclosure or ring-feature, a word that carries the kind of affectionate familiarity reserved for landmarks that have long been absorbed into the working vocabulary of a place. The subcircular plan of the hut is consistent with a tradition of small, functional shelters found across the upland and bogland margins of the Iveragh Peninsula, where the landscape was worked by people who needed somewhere to take cover or store tools without constructing anything more permanent. The surrounding peat, which has encroached on and preserved much of what lies beneath it across this part of Kerry, gives the site a kind of suspended quality, as though the knoll and its little structure have simply been waiting out the centuries while the bog grew up around them.
