The one at Ballaghaline, on the Clare coast, is a near-perfect square, which is unusual enough to give you pause. Roughly 25 by 26 metres, its perimeter wall has long since been swallowed by grass, but the geometry remains legible underfoot, a formal shape sitting quietly in rough pasture and karstic pavement a little under 250 metres from the shore. Karstic pavement, the exposed, fissured limestone so characteristic of this part of Clare, gives the surrounding landscape a skeletal, lunar quality, and against that backdrop the enclosure reads as something deliberate and considered, placed here for reasons that are no longer entirely clear.

The enclosure is not isolated. It sits within a broader field system, and two cashels, the Irish term for a stone-walled ringfort, lie within sight: one around 73 metres to the south-west, another roughly 110 metres to the north-east. That clustering suggests a settlement landscape of some complexity, where different structures served different functions, probably across an extended period. A later field wall has been built along the south-west side of the enclosure, showing that the site remained in active agricultural use long after its original purpose was forgotten or abandoned. Whoever laid that wall simply incorporated what was already there, pressing an older boundary into a newer arrangement of land.
