A grass-covered mound sitting quietly in pasture near Clonkerdin in County Waterford conceals what was once a prehistoric cooking site, now vanished entirely from the surface. The mound, roughly fifteen metres across and about a metre high, is composed of broken and burnt stones, which is the characteristic signature of a fulacht fia. These are among the most common archaeological monuments in Ireland, and the working theory is that they functioned as outdoor cooking stations: stones would be heated in a fire and then dropped into a water-filled trough, bringing the water to a boil and allowing meat to be cooked. The burnt and shattered stones, discarded after repeated heating and cooling, accumulated over time into the low, distinctive mounds that survive across the Irish countryside today.

This particular site attracted attention in 1885, when an investigation uncovered a hearth and a wooden trough beneath the mound, exactly the kind of features the fulacht fia model predicts. The findings were published by J. Quinlan in the Journal of the Royal Society of Antiquaries of Ireland, under the title 'Cooking places of the Stone Age in Ireland'. It is one of the earlier documented excavations of such a monument in Waterford, and the discovery of a surviving wooden trough was notable, since organic materials rarely endure well in Irish soils. The site appeared on the 1927 edition of the Ordnance Survey six-inch map, which is how its identification as a fulacht fia was formally preserved, though by that point the mound itself was already long unexcavated. Today, nothing is visible at ground level.
