It measures roughly 21.5 metres on its longest axis, and to most eyes it would read as nothing more than a slight rise in boggy ground. What it actually represents is a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically identified by the characteristic horseshoe-shaped mounds of fire-cracked stone that accumulate when heated rocks are repeatedly plunged into water-filled troughs to bring them to the boil. The association with marshy or waterlogged ground is typical; these sites were deliberately positioned near reliable water sources.

What makes this particular spot quietly notable is not the mound itself, which is modest even by the standards of a monument type that tends toward the unshowy, but its immediate context. It lies around eighty metres east of a well, which fits the pattern of fulachta fia clustering near water, and a second fulacht fia sits just twenty-five metres to the south-east. Such pairings or groupings are not unusual, and they raise questions that archaeology has not yet fully settled: whether closely spaced sites represent repeated seasonal use of a favoured location over generations, or more concentrated activity across a shorter period. The burnt mounds themselves are the accumulated waste of the process, discarded stone that lost its heat-retaining capacity after too many cycles of fire and water.
