The mound measures roughly 19 metres by 18 metres and stands 1.7 metres high, with a 4-metre opening facing north. It is a fulacht fia, the term used for a type of prehistoric cooking site found in great numbers across Ireland, typically consisting of a trough for heating water and a surrounding mound built up from the shattered, fire-cracked stones discarded after repeated use. The horseshoe or kidney shape of the mound is characteristic of the type, formed precisely because material was thrown outward from the central working area over many uses.

This particular site was recorded by a researcher named Bowman in 1934, who noted it along with a second fulacht fia on land then belonging to a P. Duane. The two sites were listed together, suggesting they may have been recognised as a related pair rather than an incidental clustering. Fulachta fiadh are generally associated with the Bronze Age, though the precise function of individual sites continues to be debated; cooking, bathing, textile processing, and brewing have all been proposed at various points. What is consistent across the type is the scale of effort involved, the accumulation of fractured burnt stone representing dozens or hundreds of individual heating episodes carried out over time.
