What makes it quietly arresting is that whoever built it used the landscape itself as one of its walls: the southern boundary is not constructed at all, but formed by the vertical face of naturally outcropping rock. The builders needed only three walls of their own making, and the hill provided the fourth.

Those three walls survive as collapsed drystone construction, the technique of fitting stone upon stone without mortar, common across the upland west and south of Ireland. The remains measure roughly 3.7 metres north to south and 2.9 metres east to west, making the interior a modest space, small enough to suggest a shelter rather than a dwelling of any permanence. The walls now stand only about 35 centimetres high, with a thickness of around 60 centimetres at their base, the upper courses long since tumbled inward. Rubble is scattered across the western half of the interior, likely the debris of that collapse. No date has been firmly established for the structure, and its precise purpose, whether seasonal shelter for a herder, a temporary working space, or something else altogether, remains open.
