The Burren's limestone pavement is not short of ancient monuments, but this one occupies an unusually commanding position, looking out over a valley to the south-east, with a circular cashel, a type of dry-stone walled enclosure common in early medieval Ireland, sitting roughly twenty metres to the south. The two structures together suggest a small nucleus of activity on this bleak, windswept plateau.

The enclosure measures approximately thirty-two metres by thirty-two metres, defined by double-faced battered walls, meaning walls that taper as they rise, broader at the base and narrower at the top, a technique associated with structural stability in dry-stone construction. At their best-preserved points, the walls reach a height of around 1.8 metres, though they narrow from roughly 1.5 metres wide at the base to 0.8 metres at that maximum height. Portions of the west, north, and east walls survive; the south is less intact. A second rectilinear area is attached at the western side, suggesting the enclosure may have been extended or subdivided at some point. The site was brought to official attention by Tim Bowmer, whose 2019 survey documented it formally for the first time.
