This is a fulacht fia, a type of prehistoric cooking or heating site found in enormous numbers across Ireland, typically dated to the Bronze Age. They work on a simple principle: stones are heated in a fire, dropped into a water-filled trough to bring it to a boil, and discarded once they crack from the thermal shock. Over time, those shattered, blackened stones accumulate into the horseshoe-shaped mounds that still dot fields, riverbanks, and boggy ground throughout the country.

This particular example measures roughly 9.4 metres east to west and 5.6 metres north to south, rising to a modest 0.55 metres above the surrounding ground. The opening, about 1.6 metres wide, faces the river, which would have served as the obvious water source for whoever used it. The mound is composed of the characteristic heat-shattered stones and charcoal-enriched soil that define the type. At the tip of the eastern arm, erosion from the river has cut into the mound, exposing traces of burnt material, giving a small but direct glimpse into the accumulated evidence of repeated use. The site sits within a network of field boundaries, so the landscape around it has been worked and reworked across many centuries, yet the mound itself has survived.
