Yet buried within it is a record of repeated, deliberate fire: stones heated until they fractured, dumped and left to accumulate over time into a roughly circular spread roughly thirteen and a half metres across. These are the calling cards of prehistoric cooking or industrial activity, preserved not by any grand monument but by their own stubborn bulk.

The mound came to light not through targeted fieldwork but as a consequence of an electricity substation being planned nearby. Archaeological test trenching carried out in 2002, reported by Ní Loingsigh, sliced into the eastern portion of the feature and revealed something telling about its internal structure: the soil was at its blackest and most charcoal-dense towards the centre, grading outward to an orange-brown at the edges, the colour shift suggesting a long history of burning concentrated at the core. The western section of the mound lay beyond the development boundary and was left undisturbed. The site belongs to a class of monument known as a burnt mound, or fulacht fia in Irish, a term covering the kind of mound typically formed by repeatedly heating stones in a fire and plunging them into water, presumably to boil it, though the exact purposes, cooking, bathing, dyeing, brewing, remain debated. That this particular mound sits only about thirty metres from a second fulacht fia site adds some weight to the idea that this stretch of slope was a place of repeated, perhaps specialised activity rather than a single isolated episode.
