What makes it worth a second look is the layering of its construction: not one perimeter wall but two, one built outside the other along the south-east arc, suggesting that whoever lived or worked here at some point decided the original boundary was not sufficient, or perhaps needed reordering.

The site is a cashel, the term used for a ringfort built from stone rather than the earthen banks more commonly seen across Ireland. Ringforts in general were the farmsteads of early medieval Ireland, typically enclosing a family's dwelling and outbuildings within a defended perimeter. This one measures roughly 27.5 metres in diameter, its main wall constructed with a rubble core and small boulders forming low inner and outer faces, a technique known as revetment. In several places the wall has slumped or collapsed, spreading to nearly twice its original width. The secondary wall along the south-east, built with an inner stone facing and terminating in what is described as a cusped entrance feature at the east, was clearly added after the original enclosure was established. A gap in the boulders at the south-south-west may mark where people originally passed in and out. Inside, sitting slightly east of centre, is a rectangular drystone structure about seven metres by six, with its own entrance facing south. Drystone construction means no mortar was used; the walls hold together through the careful placement of stone alone.

The site sits where cultivable slope meets boggy ground, which is a pattern seen repeatedly in early medieval settlement across upland Ireland. The marshy area to the west would have been a practical boundary in itself, and the mountain rising behind provides a natural frame. The two-phase construction, with an entrance arrangement that was clearly rethought at some point, gives the place a biographical quality, a sense of a settlement that was adapted over time rather than built all at once and abandoned.
