What remains is the remnant of a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically consisting of a trough, a hearth, and a mound of fire-cracked stones left over from repeated use. The stream that once fed this particular site has since been diverted, and the surrounding ground is heavily overgrown, lending the place the quality of something that has quietly slipped out of the world.

Fulachtaí fia are most commonly associated with the Bronze Age, roughly 1500 to 500 BC, though some examples date earlier or later. The standard interpretation is that stones were heated in a fire and then dropped into a water-filled trough to bring it to boiling point, most likely for cooking meat. The distinctive horseshoe-shaped mounds of shattered, blackened stone that mark these sites are a common feature of low-lying, waterlogged ground throughout Ireland. At Ceann Droma, local knowledge adds a detail that archaeology alone could not: a portion of the burnt material was removed at some point and used as hardcore for roadmaking. It is a mundane fate that has befallen many such sites, the ancient debris of prehistoric kitchens pressed into service beneath modern tarmac, their identity unremarked by those who shifted them.
