Its surface is naturally pocked, but centuries of cattle using it as a scratching post have worn it to a smooth polish. It is a small thing, but it captures something of the long, unbroken continuum between early medieval farming life and the working pastureland the site still sits within today. A cashel is a type of ringfort defined by a stone wall rather than an earthen bank and ditch, and this one sits near the top of a gentle south and west facing slope, with open views stretching from south to north-west across the Clare landscape.

The enclosure is almost perfectly circular, measuring roughly 30 metres across at its widest points. Its defining wall has long since collapsed and spread, surviving now as a grassed-over band of stone roughly 2.8 to 3.7 metres wide and only modestly proud of the surrounding ground. A few original facing stones are still visible at the southern arc. Two upright stones remain on the wall spread: one at the west, oriented north-west to south-east, and the polished limestone post at the north-east. The site was recorded on Ordnance Survey six-inch maps in both the 1840 and 1916 editions, noted as a hachured enclosure, a cartographic convention for marking earthworks and similar raised features. A series of small rectangular fields extends immediately to the east and south of the cashel, a field system that appears to relate directly to the enclosure itself. A second cashel lies approximately 48 metres to the north-north-west, suggesting this corner of Clooneen was once a settled and organised agricultural landscape, its layout still partially legible in the modern field boundaries around it.
