The one under discussion here is a cashel, a type of ringfort built from stone rather than earth and timber, and it occupies a slight rise with limestone pavement spreading away to the west. That pavement is a reminder of the broader Burren landscape, where the underlying geology keeps breaking through whatever thin covering of soil or grass the land manages to hold.

The structure is subcircular in plan, measuring roughly 23 metres north-north-east to south-south-west and 19 metres west-north-west to east-south-east. Its defining feature is a double-faced wall, meaning two parallel outer skins of laid stone with rubble between them, originally about 1.6 metres wide. Along the eastern side, where the monument has fared best, the wall-faces still stand to around half a metre, and a scarp, a natural or man-made slope in the ground surface, reinforces the boundary and reaches over a metre in height at the north-east. Elsewhere the wall has largely collapsed into a spread of rubble three to four metres wide and about a metre high, swallowed by vegetation. Several large boulders along the eastern arc appear to have been deliberately incorporated into the outer wall-face, particularly one at the north-east, suggesting the builders were working the available limestone to their advantage rather than clearing it away. The cashel was already recorded on the first edition Ordnance Survey six-inch map of 1842 and was noted again, with hachuring to indicate its raised ground, on the later Cassini edition of 1920, so its presence in the landscape has been acknowledged for well over a century even as it has continued to deteriorate.
