It is the kind of site that rewards the imagination more readily than it rewards a visit, since it is recorded as inaccessible, half-buried in undergrowth on the eastern bank of the water.

The mound is believed to be a fulacht fia, a type of prehistoric cooking site found across Ireland in considerable numbers. The term refers to a horseshoe-shaped mound of burnt and fire-cracked stone, typically found near a water source, which is precisely the situation here. The working theory, broadly accepted among archaeologists, is that stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil, probably for cooking meat. The resulting piles of discarded, shattered stone form the mounds we see today, and they date most commonly to the Bronze Age. This particular example appears on a 1943 Ordnance Survey six-inch map, where it is marked simply as a mound, which suggests it was visible and recognisable at that point even if its purpose was not necessarily labelled. Whether it had already been identified as a fulacht fia by then, or whether that classification came later, the site has since been swallowed further by the surrounding vegetation.
