There is nothing to see from the roadside, no marker, no mound, no obvious break in the landscape. The site exists, for most purposes, only as a rumour passed along by local farmers who have noticed the scorched material turning up in the furrows.

What they are glimpsing is the residue of a fulacht fia, a type of site found in enormous numbers across Ireland and dating primarily to the Bronze Age, roughly 1500 to 500 BC. The name, loosely translated from Irish, refers to a cooking place, and the mechanics were straightforward: stones were heated in a fire and then dropped into a water-filled trough to bring it to a boil. The cracked and fire-shattered stones were discarded in a heap nearby, and it is these heaps, typically forming a low horseshoe-shaped mound around the trough, that survive as the most common physical trace. At Kilcummer, even that mound is gone, levelled at some point by agriculture, leaving only the burnt and fractured stone below the topsoil. When the plough disturbs it, the dark scorched material becomes briefly, improbably visible, a few seconds of the Bronze Age turned up into the light before being buried again.
