The enclosure measures roughly twenty metres east to west, and what gives it an odd geometry is its straight eastern side, which turns out not to be original at all but formed by a later field wall that was built across or alongside the older structure. The result is a shape that only makes sense once you understand it as an accidental collaboration between different eras of farming and settlement.

The enclosure is defined by a grassed-over stone wall, the kind of low, vegetation-softened boundary that the Burren produces in abundance, where thin soil and relentless limestone mean that walls sink slowly into the ground rather than tumbling dramatically. It sits on a gentle south-facing slope near the eastern end of a broad karst plateau, karst being the distinctive limestone landscape characterised by exposed rock pavement, grikes, and clints, and very little surface water. The enclosure is not an isolated feature but part of an extensive multiperiod field system, meaning that field boundaries from different periods of use, possibly spanning prehistoric, early medieval, and later agricultural activity, overlap and intersect across the same ground. Contemporary field boundaries adjoin the enclosure at its south-west and north-west corners, suggesting it was once integrated into a working agricultural layout rather than set apart from it.
