The inward collapse is the giveaway: it suggests the structure was originally corbelled, a technique in which each course of stones is laid slightly inward over the one below until the courses eventually meet at the top, forming a self-supporting dome without any mortar. When a corbelled roof fails, it tends to fall in rather than out, and that is precisely what has happened here.

The hut measures five metres at its widest point, with walls roughly a metre thick and still standing to a metre in height in places. A probable entrance, just under a metre wide, faces east. It sits on the eastern side of the gully, about twenty metres west of another recorded site in the same upland landscape. The structure was documented by F. Coyne in a 2006 study, "Islands in the Clouds: an upland archaeological study on Mount Brandon and the Paps, Co. Kerry," published by Kerry County Council in association with Aegis Archaeology. That study surveyed the archaeological remains scattered across these mountain landscapes, where altitude and remoteness have left an unusual number of early structures relatively undisturbed. Huts of this kind are associated with seasonal pastoral activity, with early Christian hermitage traditions, or simply with the practicalities of working at height in a landscape where shelter mattered and timber was scarce.
