On a mountain stream in the upper Tay river valley, in the Comeragh uplands of County Waterford, a low grass-and-furze-covered mound sits quietly in a natural basin. Eight metres across and only half a metre high, it is easy to dismiss as a trick of the boggy terrain. But the broken, fire-cracked stones beneath the vegetation tell a different story: this is a fulacht fia, a type of prehistoric cooking site found in the hundreds across Ireland, and one of two sitting within twenty metres of each other on opposite banks of the same stream.

Fulachtaí fia (the plural form) are among the most common archaeological monuments in the Irish landscape. The basic method involved heating stones in a fire, then dropping them into a water-filled trough to bring it rapidly to the boil, which could be used for cooking meat, processing hides, or possibly bathing. The spent, shattered stones were raked aside after each use, and over generations these discards accumulated into the characteristic horseshoe-shaped mounds that survive today. The paired nature of this site is quietly intriguing: a second fulacht fia lies roughly twenty metres to the south-west, on the far side of the stream, suggesting repeated or concurrent activity at this spot. The location in a natural basin beside running water is entirely typical; water supply was essential to the process, and upland streams offered both convenience and seclusion.
