It measures just 3.45 metres in diameter, its drystone walls still partly visible beneath a covering of sod, and a pair of upright stones at the north marks what was once a doorway, half a metre wide. That entrance, that careful placement of uprights, speaks to deliberate construction rather than natural arrangement, though whoever built it and precisely when remains unrecorded.

The site belongs to a broad and ancient tradition of small stone-built hut sites found across the uplands and marginal lands of Kerry and beyond. Drystone construction, which uses no mortar and relies entirely on the careful fitting of stones, is one of the oldest building techniques in Ireland, and structures of this kind could date from any period between the early medieval era and the post-medieval, depending on context. On the Iveragh Peninsula, such sites are often associated with seasonal activity, pastoral farming, or the movement of people and livestock between lowland and upland grazing areas. The Carhan river valley, running out towards Cahersiveen, would have been part of a well-travelled landscape for centuries, and the lower slopes of Rehill were evidently worked and inhabited long before any written record catches up with them.
