This type of monument, known in Irish as a cashel, is a stone-walled equivalent of the more familiar earthen ringfort, built directly on the bare karst where digging a ditch would have been impractical. What gives this particular example an extra layer of interest is not just its survival but what surrounds it.

The enclosure is roughly circular, with internal measurements of around seventeen metres north-northeast to south-southwest and just under fifteen metres in the other direction, suggesting a modest but clearly defined domestic or agricultural space. The wall itself, where it survives above its base, was constructed from large flat stones, some roughly seventy by fifty centimetres, laid with intermittent facing on both inner and outer sides. On the eastern side the stone has been robbed away entirely to ground level, a common fate for old structures in areas where building material was scarce and convenient, and a later field wall has been built east to west across the interior, cutting through the original space. To the south-west, only about thirty-four metres away, a second cashel stands with the remains of house structures of uncertain date still visible within it. The pairing of two such enclosures in close proximity is a reminder that the Burren's landscape, apparently austere, was once densely organised and inhabited.
