It is subcircular in plan and corbelled, meaning its walls curve inward and its roof is formed entirely from overlapping stones, each layer projecting a little further than the one below until the gap closes at the top, no mortar and no timber involved. This technique, ancient and practical in equal measure, produced a structure that could be raised by a single person with patience and an eye for balance, and that could outlast almost any other kind of building in the Irish upland landscape.

The site sits at An Baile Breac on the Dingle Peninsula, a stretch of country long studied for the density and variety of its early remains. The hut does not stand entirely alone. Roughly six metres to the south lies a small rockshelter, a natural feature that may well have been used in conjunction with the structure. A short distance to the west, what appears to be a sheep-shelter has been constructed directly on the ruins of a second hut, a detail that quietly collapses several centuries into one another: an earlier habitation repurposed, its stones reused, its outline still faintly legible beneath the later work. The 1986 archaeological survey of the Corca Dhuibhne region by J. Cuppage brought the cluster to wider attention, and it remains one of those small, compound sites where the landscape has been worked and reworked across generations in ways that are easier to feel than to date precisely.
