It is easy to overlook, easy to mistake for a natural rise in wet ground, but the shape and the burnt material give it away. This is a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically beside water and in low-lying, boggy terrain.

Fulachtaí fia, as they are known in the plural, are among the most commonly recorded prehistoric monuments in Ireland. The general interpretation is that they functioned as outdoor cooking places, probably during the Bronze Age, where water was boiled in a timber or stone trough by dropping fire-heated stones into it. The stones, cracked and blackened by repeated heating and sudden cooling, were discarded to form the characteristic horseshoe or kidney-shaped mound that survives today. The opening in the mound typically marks where the trough once sat. What makes the Kilmacurrane site quietly notable is not just its own presence but the proximity of a second fulacht fia, recorded roughly thirty metres to the east. Two such monuments in close proximity, both beside water and marshy ground, suggest repeated use of this particular stretch of landscape over time, or perhaps activity by a community large enough to require more than one such facility.
