The only reason anyone knows it is there at all is a single aerial photograph taken on 16 July 1971, in which a cropmark, the faint differential in plant growth that betrays buried structures beneath the soil, traces out the circuit of what was once a defined, enclosed space, complete with an entrance opening in its eastern quadrant.

Cropmark enclosures of this kind are scattered across Ireland, and many remain unexcavated and undated. Without digging, it is impossible to say with certainty what purpose this one served, whether it was a domestic settlement, a ceremonial space, or something else entirely. What the 1971 photograph does preserve is the enclosure's basic geometry: a near-perfect circle, an orientated entrance, and, just to its west, a small quarry that had already fallen out of use by the time the aerial survey was carried out. Whether the quarry and the enclosure are historically connected is unknown, but their proximity gives the field an unassuming layering of past activity that would be easy to walk across without suspecting a thing.
