It measures between sixteen and twenty metres across, and within that space the ground is clear of the outcrop that surrounds it on all sides. No walls remain, no earthworks, no obvious structural trace. Just an absence, and the faint suggestion that the absence means something.

The site was recorded on the Ordnance Survey six-inch maps of both 1840 and 1920, where it was marked with hachures, the small radiating lines surveyors used to indicate an enclosure or raised feature in the landscape. That it appeared on two separate editions of the map, eighty years apart, suggests it was legible enough in the nineteenth and early twentieth centuries to be worth noting. By the time of an on-the-ground inspection in 1999, however, the enclosure had reduced to this single telling detail: a circular patch of soil from which the surrounding rock outcrop is conspicuously absent. The most likely explanation is that the enclosure was once defined by a low earthen or stone bank, and that over centuries of woodland growth and decay, what remains is only the footprint, preserved as a gap in the natural rock pattern rather than as any built feature.

Coppiced hazel woodland, where trees are periodically cut to the base to encourage regrowth, can be dense and disorienting at ground level, and the rocky terrain of this part of County Clare adds to the difficulty of reading the landscape. Without the map record to orient a visitor, the circular clearing could easily pass unnoticed, or be mistaken for a natural quirk of the geology rather than a human imprint on it.
