It is a fulacht fia, a class of site found in the thousands across Ireland, typically appearing as a low, horseshoe-shaped mound of fire-cracked stone and charcoal-dark earth. The working theory, broadly accepted though still debated, is that these were ancient cooking sites, where stones were heated in a fire and then dropped into a water-filled trough to bring it to boiling point. Some researchers have proposed additional uses, from textile processing to bathing, but the burnt and shattered stone tells the same story regardless: repeated, intensive heating over time.
