Its western edge follows the line of a mountain stream. The enclosure is substantial enough to feel purposeful, yet its precise origin sits somewhere between archaeology and local memory, which is often exactly where the most interesting things do.

Local tradition gives the place the name "Buaille Caiseal", and associates it with the pounding of cattle by the caretaker of the Puxley family, West Cork landowners whose name surfaces in various corners of the Beara Peninsula's history. A buaille, in Irish land use, was a summer grazing place or milking ground, and the name suggests a site adapted over time for pastoral impoundment rather than built as a monument. Within the larger enclosure, a smaller subcircular enclosure, roughly 14 metres by 12, sits in the northern half atop a slight terrace beside a rock outcrop. Its interior, level to the east and south, is defined by a stone wall on the east side, a stone-faced scarp to the south, and a natural rise to the west that serves as its own facing. By the early twentieth century it was recorded on Ordnance Survey mapping, its interior already heavily overgrown with bracken. A second small rectangular structure, visible on an 1901 OS six-inch map about 60 metres to the west, appears to have been lost to a modern trackway, leaving only its cartographic ghost behind.
