The structure is a cashel, the Irish term for a ringfort built from stone rather than earth and timber, and what survives here is largely the ghost of a wall, grass-covered stone spill and occasional facing stones betraying where a double-faced barrier once stood.

The cashel occupies a gentle east-facing slope, orientated so that its interior would have caught the morning light. Its dimensions are modest but clear enough to measure: the interior runs roughly 20.5 metres on the northwest-to-southeast axis and just under 20 metres on the other, while the overall footprint stretches to around 25 by 24 metres. Where the original double-faced wall, essentially two parallel skins of upright stone with rubble packed between them, can still be traced at the west-northwest, it measures about 2.3 metres in width, though it stands no more than half a metre high today. The cashel sits within a larger multiperiod field system, meaning the landscape around it accumulated boundaries, enclosures, and divisions across several different eras, with the ringfort representing just one layer of a much longer agricultural and social history in this part of the Burren region.
