One of them is particularly easy to overlook: a roughly built rectangular enclosure, barely a metre and a half across in either direction, with walls that survive to around eighty centimetres. It is not a dwelling, not a field boundary, not a souterrain. Its purpose, like much of what people once did on these uplands, is not immediately obvious.

The enclosure is one of four drystone structures grouped together at this elevation on the Iveragh Peninsula. Drystone construction, in which stones are fitted together without mortar, was the default technique across much of early Irish upland building, practical in landscapes where dressed stone and lime were hard to come by. The site sits north of a hut within the cluster, and its modest dimensions suggest something functional rather than defensive or ceremonial, though what exactly it held or served is not recorded. The Iveragh Peninsula has yielded a considerable range of upland archaeology, from early medieval pastoral settlements to booley huts used by transhumant farming communities who moved cattle to higher ground in summer, and this grouping fits into that broader, still-incompletely-understood pattern of mountain land use.
