What makes the arrangement quietly arresting is its relationship to its neighbour: rather than standing alone, this suboval enclosure, roughly 48 metres east to west and 38 metres north to south, is attached directly to the eastern side of the cashel, as though it grew from it or was added to it in a second thought.

A cashel is a type of early Irish stone ringfort, typically a circular or near-circular enclosure defined by a dry-stone wall, often associated with a farmstead or a person of local standing. The cashel here is described as subsquare, meaning its plan sits somewhere between a square and the more typical rounded form, which is itself an unusual detail. The suboval enclosure beside it is defined by a stone wall and occupies a promontory position that would have commanded clear views across the landscape below. The site was brought to the attention of the National Monuments Service by Michael Gibbons, a field archaeologist well known for identifying and recording sites across the west of Ireland.
