Its defining bank of stone and earth, measuring roughly 1.6 to 2.1 metres wide and less than a metre high, has been partially swallowed by a later field wall along one side, and what remains visible is largely a gentle scarp to the north and a faint low stony bank curving around the western edge. The interior spans approximately 19 metres north to south and 14 metres east to west, small enough that the whole thing might be mistaken for a natural depression or an old animal pen. Only the probable original entrance to the north-east, a narrow gap of around 0.8 metres, hints that something more deliberate was once intended here.

The enclosure sits within a far larger context that gives it real weight. Spreading across roughly 8 square kilometres of this Burren upland, an extensive multiperiod field system surrounds it, one that accumulated across many generations and many different phases of land use. Such field systems in the west of Ireland preserve evidence of farming, settlement, and territorial organisation stretching back centuries, sometimes millennia, with boundaries laid down in one era reused or overwritten in the next. About 60 metres to the south-south-east, within the same system, stands a cashel, a type of stone-walled enclosure typically associated with early medieval settlement and farming, usually circular and built to define a farmstead or small community. The proximity of the two structures, along with the broader field system enveloping them, suggests this corner of Slieve Elva was once a considered, organised landscape rather than marginal ground. The views from the site, commanding from west-south-west to north-east, would have made it a useful as well as habitable position.
