The example at Lislehane in County Cork sits quietly in pasture to the west of a marshy area, presenting itself as a low horseshoe-shaped mound of burnt and fire-cracked stone. A fulacht fia, to give the type its due, is the remains of an ancient cooking site, typically Bronze Age in date, where stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil. Over time, the shattered, heat-spent stones were raked out and piled up around the trough, creating that characteristic crescent or horseshoe shape.

The Lislehane mound measures roughly ten metres on its longer northeast to southwest axis and just under nine metres across, rising to a modest height of around half a metre. Its opening, about three and a half metres wide, faces west-northwest, broadly towards the low-lying wet ground nearby. That proximity to marshy terrain is no coincidence; a reliable water source was essential to the whole operation, and such sites tend to cluster wherever the ground holds water. What makes the Lislehane location quietly interesting is that a second fulacht fia lies approximately one hundred metres to the south. Whether the two were used at the same time or represent different episodes of activity across a stretch of prehistoric centuries is not something the visible remains can answer on their own, but the pairing suggests this particular corner of North Cork was a place people returned to, repeatedly, for purposes that required fire, water, and stone.
