It is a cashel, a type of ringfort built from dry-stone walling rather than earthen banks, and at around 25 metres in diameter it would once have enclosed a farmstead, probably dating to the early medieval period. What makes this particular example quietly interesting is partly its status: it appears on the 1915 edition of the Ordnance Survey six-inch map as a solid line, but its identification as a cashel remains tentative, recorded as a possibility rather than a certainty.

The site lies on the eastern side of the valley that runs between Gleninagh Mountain and Cappanawalla Hill, within a broader field system that contains several cashels and hut sites. That density of remains is characteristic of the Burren, where thin soils and a lack of later intensive agriculture have left early medieval and prehistoric landscapes unusually intact. This particular cashel was noted and reported to the National Monuments Service by Ros Ó Maoldúin, and it does not stand alone; the nearest comparable enclosure lies approximately 100 metres to the south-east, suggesting that what survives here is a fragment of a much more extensive pattern of early settlement across the hillside.
