It sits in a slight depression on a rocky terrace, roughly nineteen metres across, ringed by a drystone wall about a metre high and less than a metre wide. A drystone wall is simply a wall built from stacked stone without mortar, relying on the careful arrangement of the stones themselves for stability. What makes this one quietly puzzling is the absence of any clearly defined entrance. There are low points in the wall at the west and south, but nothing that reads as a deliberate doorway. The interior is bisected by the remnant of another low wall running north to south, and the whole space tilts almost imperceptibly downward from the centre toward the south-west. Ferns now fill much of the interior, softening the outlines further.

The enclosure raises an obvious question: what was it for? A ringfort, the most common type of circular enclosure found across Ireland, was typically a defended farmstead of the early medieval period, enclosed by an earthen bank or a more substantially built stone wall. This structure does not fit that description. The wall is narrow and roughly assembled from field stone rubble, built in much the same way and to much the same scale as the ordinary field boundaries that pattern this part of Mayo. The working interpretation is that it may have served as an animal enclosure, probably during the eighteenth or nineteenth century, a practical pen on marginal upland ground rather than anything ceremonial or ancient. That provisional dating, and the absence of any recorded historical documentation, means the enclosure occupies an uncertain place, too recent and too modest to attract the attention usually given to ancient monuments, yet too deliberately constructed to be dismissed as a casual arrangement of stone.
