About twenty-five metres across, it is defined by a stone wall that has endured long enough to remain legible from aerial photography, even if it draws little attention at ground level. What makes it quietly curious is its setting: exposed karst, the bare limestone pavement characteristic of the Burren, where thin soils, grey rock, and ancient field boundaries blur together into something that resists easy dating or interpretation.

The enclosure forms part of a much larger field system that runs along the Burren uplands between Poulbaun to the north and Rannagh West to the south. Field systems of this kind, built up over centuries of agricultural use, are a recurring feature of the Burren, where stone was always more abundant than timber and walls were the natural way to divide ground. This particular enclosure was noted by Ros Ó Maoldúin and sits within that broader pattern of land management, with an irregular field attached at its south-eastern side, suggesting it was once integrated into a working agricultural arrangement rather than serving as a purely defensive or ceremonial structure.
