It is modest in scale, roughly six metres across in either direction, and easy to overlook as just another feature of the karst landscape, where the ground itself seems to have been pulled apart into slabs and fissures. But it is precisely that setting that gives the structure its quiet interest.

The fold is built from dry-laid stone, meaning no mortar was used, just carefully stacked and fitted limestone gathered from the surrounding ground. At its best-preserved point, on the south-western arc, the wall still stands to about one metre fifteen centimetres and measures nearly a metre and a half across at the base, which is a substantial construction for what was essentially a working enclosure for sheep. A pile of rubble in the eastern quadrant marks where part of the wall has given way, though the overall oval plan remains legible. Karst terrain of this kind, common across County Clare and much of the Burren region, presented farmers with both a challenge and a convenience: the land was largely unsuitable for tillage, but the thin grass growing in the grikes between limestone slabs could support grazing animals, and loose stone for walling was always immediately to hand.
