What makes it quietly puzzling is the wall itself: wide enough to walk along, at around five metres across, yet barely ankle height on either side. A boundary that substantial was not built casually, and yet it encloses no building, no obvious ceremonial space, no feature that announces its reason for existing.

The enclosure measures approximately 65 metres north to south and 50 metres east to west, dimensions recorded on the 25-inch Ordnance Survey map. Its rubble stone wall, low and spread wide, sits in a landscape that bears further marks of human industry: there is evidence of quarrying in the surrounding area, which may well explain where the stone came from, and perhaps suggests that the enclosure and the quarrying activity belong to the same period of use, even if what exactly was being enclosed remains unclear. Enclosures of this kind, built from gathered field stone and set into marginal or rough ground, appear across Ireland in various periods, serving functions that range from livestock management to land division to uses now difficult to read from the physical remains alone.
