Three metres across, its walls survive to no more than half a metre in height on the best-preserved side, which faces north. No entrance has been identified. No internal features remain. What it leaves behind is just enough to prompt a question rather than answer one.

The detail that makes it worth pausing over is the stonework itself. The stones appear to be ramped inwards, which is consistent with corbelling, a technique in which successive courses of stone are laid so that each projects slightly beyond the one below, eventually closing the roof without the need for timber or mortar. It is a construction method with deep roots in Irish prehistory and early medieval building, and its possible presence here, even in such a fragmentary state, suggests this was a deliberately and carefully made shelter rather than a casual enclosure. The structure was documented as part of a broader archaeological study of upland Kerry, published in 2006 under the title "Islands in the clouds", which examined the archaeological landscape of Mount Brandon and the Paps. Upland areas like this tend to preserve traces of activity that lower ground, subject to centuries of tillage and development, has long since erased, and small huts of this kind may represent seasonal shelters used by those moving livestock to higher pastures, or possibly something with a more solitary or ritual purpose.

The surviving northern arc of wall is the most legible part of the structure now, and it is there that the inward ramping of the stones is most apparent. Beyond that, the site offers very little in the way of readable detail, which is itself part of what makes it interesting: a three-metre circle of carefully laid stone, roofless and entrance-less, sitting quietly in upland Kerry with no firm date and no certain explanation.
