The structure is a cashel, the Irish term for a stone-walled ringfort, a type of enclosed farmstead built predominantly during the early medieval period. What makes this one quietly compelling is not any single dramatic feature but the way it sits within a wider field system, connected to the surrounding land by walls that radiate outward from the cashel itself at four compass points, as though the enclosure were the hub of something larger and longer-lasting.

The cashel is oval in plan, measuring roughly 41 metres by 30 metres on the outside, with a drystone perimeter wall between two and four metres wide. The wall survives to an internal height of up to 0.8 metres and an external height of up to 1.8 metres in places, with the outer face still legible across most of the circuit. The section at the east-southeast is more roughly built than the rest, suggesting either an older phase of construction or a later repair that did not match the original quality. Against the interior of the perimeter, at the southwest and southeast, lie the foundations of two possible house sites, the kind of small rectangular or sub-oval structures that would have sheltered a farming household and their dependants. A cattle pen was added against the south-southwest section at some later point, and the upright stones visible at the southern extent are modern insertions rather than original fabric. The enclosure was already recorded on the Ordnance Survey six-inch maps of 1840 and 1916, marked with hachures indicating a raised or earthwork feature, though its origins are considerably older than either survey.

The site sits on commanding high ground with open views to the north and west, interrupted only by rising ground to the east and south-west. That positioning, close to a cliff edge and looking outward over the landscape, was unlikely to be accidental. Early medieval farmers in Ireland chose elevated locations for reasons of visibility and drainage as much as defence, and the field walls that extend from this cashel suggest it remained a working centre of agricultural organisation long after whoever first built the enclosure had gone.
