Piled on top of it now is debris from a field fence clearance, the kind of agricultural tidying-up that happens all the time across rural Ireland. But underneath that mundane accumulation is something considerably older: a fulacht fia.

A fulacht fia is a type of ancient cooking site found throughout Ireland, typically consisting of a horseshoe-shaped mound of fire-cracked stones beside a trough or pit. The general method involved heating stones in a fire and dropping them into a water-filled trough to bring it to the boil, then using the hot water to cook meat. They are among the most commonly recorded prehistoric monuments in the country, dating broadly to the Bronze Age, and they tend to cluster near water sources, which explains why this one sits where bog meets rough grazing ground. The Toormore example has been levelled over time, its original mound reduced, and the characteristic spread of burnt and shattered stone that gives these sites their distinctive dark, scorched appearance now lies low in the landscape.
