The enclosure is subrectangular in shape, measuring roughly fifteen metres north to south and eleven metres east to west, defined by a wall that has persisted in the landscape long enough to attract the attention of the Ordnance Survey when their teams moved through this part of Connacht in the early 1840s.

The 1842 edition of the OS six-inch map, one of the first systematic large-scale surveys of the Irish countryside, marks the enclosure with hachuring, a cartographic convention used to indicate earthworks or raised features, just to the east of a triangulation station. The fact that it appears on that early survey places it firmly in the pre-Famine landscape, though enclosures of this general type in Clare can have origins stretching back considerably further. The semi-karst terrain, where limestone lies close to or breaks through the surface in irregular patterns, is characteristic of parts of the Burren and its margins, and the rough pastureland here would have made the deliberate bounding of even a small area a meaningful act. Whether the enclosure served an agricultural function, a domestic one, or something else entirely, the notes do not say.
