It is a fulacht fia, a type of prehistoric cooking site found in great numbers across Ireland, typically consisting of a trough dug into the earth, a hearth for heating stones, and a mound of the cracked, fire-shattered stones that accumulated over repeated use. This particular example measures roughly 7.2 metres long, 7.3 metres wide, and just 0.35 metres high, its opening, about 3 metres across, oriented towards the south-southeast.

What makes this site quietly notable is its immediate neighbour. Just one metre to the southwest lies another fulacht fia, making this one of a close pair, the two mounds almost touching in the same patch of boggy ground. Fulachtaí fia are most commonly dated to the Bronze Age, though some sites saw use across longer periods, and they tend to cluster near water sources, which the marshy setting here would readily have provided. The proximity of two such monuments suggests this spot was a place of sustained and deliberate activity rather than casual, one-off use, though whether the two mounds represent simultaneous or successive occupation is the kind of question the ground alone cannot easily answer.
