It measures roughly 26 metres east to west and 20 metres north to south, subrectangular in shape, and it sits close enough to its larger neighbour that the two almost certainly belong to the same period of occupation. A cashel, for those unfamiliar with the term, is a dry-stone ringfort, a type of enclosed settlement common across early medieval Ireland, typically built to protect a farmstead and its inhabitants. This smaller enclosure beside it is the kind of feature that rarely draws attention on its own, yet its presence raises questions about how the wider settlement was organised and used.

The enclosure was noted by Conn Herriott and is visible on satellite imagery from the Digital Globe dataset captured between 2011 and 2013. Beyond that, the record is spare. What it does confirm is that the wall survives, that its relationship to the adjacent cashel is likely contemporary rather than incidental, and that this corner of the Burren landscape preserves at least two distinct but related features from what was once a functioning early settlement. The Burren's thin soils and long tradition of pastoral farming have helped preserve such structures, since deep ploughing was rarely possible and the land has often remained in light agricultural use across the centuries.
