To a passing eye it looks like nothing at all, just a slight rise in the turf. Beneath and within it, however, lies a scatter of fire-cracked stone and charred material that marks it as a fulacht fia, one of the most common yet still somewhat mysterious monument types in the Irish archaeological landscape.

Fulachtaí fia are prehistoric cooking sites, typically Bronze Age in date, found in their thousands across Ireland. The usual interpretation is that stones were heated in a fire and then dropped into a water-filled trough, bringing the water rapidly to a boil for cooking meat. The process left behind a characteristic horseshoe-shaped mound of shattered, heat-fractured stone, dark with organic residue, which is precisely what survives here at Curraghcloonabro. The mound's modest height, around ten centimetres, suggests either that much of the original deposit has spread and settled over the millennia, or that this was never a heavily used site to begin with. It sits in ordinary pasture, undisturbed in any dramatic sense, just slowly merging with the surrounding field.
