The mound is a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically consisting of a burnt-mound of heat-shattered stone surrounding a sunken trough. The classic method involved heating stones in a fire, dropping them into a water-filled trough to bring it to a boil, and using that water to cook meat. This particular example follows the form closely: a U-shaped mound roughly thirteen metres across, with its opening facing south, indicating where the trough once lay.

What makes the location quietly interesting is its relationship to the landscape and to two neighbouring sites. The ground here is raised and relatively dry compared to the surrounding bog, which is itself likely the remnant of a former lake. Prehistoric communities tended to place fulachta fiadh near reliable water sources, and a lakeshore would have been ideal. The land has since been part drained for agricultural use, which has altered the character of the surroundings considerably, but enough survives to read the original logic of the site. Two further fulachta fiadh lie to the north-east, at roughly 87 metres and 97 metres respectively, suggesting this was not an isolated episode of use but part of a broader pattern of activity in the area during prehistory. Clusters of fulachta fiadh are not uncommon in Ireland, and their concentration in particular landscapes, especially boggy or waterside ground, points to repeated, purposeful return to favoured spots over long periods.
