The structure measures roughly 13.7 metres north to south and 12.4 metres east to west, making it modest in scale but precise enough in layout to suggest deliberate, purposeful construction rather than anything incidental or agricultural.

What gives the place an extra quality of strangeness is the interior itself. The ground inside the enclosure sits noticeably higher than the land around it, by somewhere between 20 and 40 centimetres, and the retaining wall of upright slabs rises about half a metre. This combination of an elevated interior and orthostatic walling, where stones are set vertically rather than laid horizontally in courses, is a feature found across a range of Irish prehistoric and early medieval enclosures, though its precise function here is not recorded. Whether it once enclosed a structure, served a ritual purpose, or marked a boundary with particular significance, the granite slabs keep their own counsel. Higher ground rises to the south and south-east, giving the site a sheltered, slightly sunken quality when approached from below.
