It measures 8.3 metres north to south and 7.5 metres east to west, rising to about 1.2 metres at its highest point, with an opening roughly 2.2 by 2.1 metres facing west. The whole thing is composed of fire-cracked and discarded stone, the accumulated debris of repeated burning.

This is a fulacht fia, a type of prehistoric cooking site found in extraordinary numbers across Ireland, with Kerry particularly well supplied with them. The typical arrangement involved heating stones in a fire, then dropping them into a water-filled trough to bring it rapidly to the boil, a process that cracked and eventually rendered the stones useless for further heating. Those spent stones were simply thrown aside, and over generations the discarded heap built up into the characteristic horseshoe shape, with the open end usually corresponding to where the trough once sat. The trough itself, often timber-lined, rarely survives above ground, but the mound it generated can endure for millennia. The siting here is entirely typical: close to a reliable water source, on a gentle slope for drainage, in open ground. Whether Bronze Age communities used these sites primarily for cooking meat, processing hides, or bathing has been debated at length by archaeologists, and the answer may simply be all three depending on the occasion.
