The example at Pinure in County Kerry is one such site, a low mound of burnt and fire-cracked stone that would be easy to walk past without a second glance, yet represents a technology in regular use here for perhaps two millennia.

A fulacht fia, the term drawn from Old Irish and loosely meaning a cooking place of the wild, typically consists of a horseshoe-shaped or spread mound of shattered stone surrounding a trough, usually timber-lined and sunk into the ground, often positioned close to a water source. The standard interpretation is that stones were heated in a nearby fire and then dropped into the water-filled trough to bring it rapidly to the boil, at which point meat could be cooked. Experiments have shown that a trough of this kind can reach boiling point in roughly twenty minutes and maintain it efficiently. The burnt and fractured stones, useless for further heating, were simply discarded to the side, building up the characteristic mound over repeated use. Most examples date to the Bronze Age, roughly 1500 to 500 BC, though some sites show evidence of use into the early medieval period. Kerry has a particularly dense distribution of these monuments, a reflection both of ancient activity and of the county's relatively good conditions for their preservation in low-lying, sometimes boggy ground. The site at Pinure fits quietly into that wider pattern, a modest trace of sustained, practical human presence in this corner of the county.
