It measures roughly eight metres long, six metres wide, and just over half a metre high, denuded now and easy to overlook. What it represents, though, is one of the most common yet persistently puzzling monument types in the Irish landscape.

This is a fulacht fia, a term used to describe the crescent or horseshoe-shaped mounds of fire-cracked stone and charcoal that appear in their thousands across Ireland, particularly in low-lying, waterlogged ground near streams or springs. The current scholarly consensus is that these sites were used for cooking, most likely by heating stones in a fire and then dropping them into a water-filled trough to bring it to the boil. The burnt and shattered stones, discarded after use, accumulated over time into the distinctive mound that survives. They date broadly to the Bronze Age, though some sites show evidence of use across multiple periods. The location at Curraclogh is characteristic: marshy ground with reliable water close at hand was precisely the kind of setting these features required. The mound here has been somewhat worn down over time, which is common for low earthworks in agricultural land, but enough remains to record its original form and dimensions.
