Croagh Patrick rises to the south, Clew Bay opens to the west, and the Nephin Beg Range stretches across the northern horizon. Whatever the enclosure was used for, its position was clearly not accidental.

The site is a rath, the most common type of early medieval ringfort in Ireland, typically built as a farmstead enclosure between roughly the fifth and twelfth centuries. This example is nearly circular, measuring approximately 23.5 metres east to west and 24.5 metres northwest to southeast. Its defining feature is an earthen bank, about five metres wide and surviving to around a metre in internal height on the northwest side. The bank is low and broad rather than dramatic, and is well preserved along its eastern to north-northwestern arc. Along part of the northern stretch, however, it has been absorbed into a modern field boundary, a common fate for earthworks that remained useful to later farmers even as their original purpose was forgotten. The interior dips gently inward from the perimeter to a wet, rush-grown centre, and there are gaps in the bank at the east-southeast and west, though whether either marks an original entrance is uncertain. Remnants of an older field bank also skirt the exterior on the southwestern to north-northwestern side, hinting at a longer history of land use around the site.
