It measures about eight metres east to west and six metres north to south, and it is all that remains of what archaeologists call a fulacht fia, a type of prehistoric cooking site once common across Ireland. The term refers to a mound of fire-cracked stone, typically found near a water source, and thought to represent the debris of repeated episodes of boiling water by dropping heated stones into a trough. Thousands of these sites survive across the island, yet each one marks the same quiet, practical act: people gathering, lighting fires, and feeding themselves or, as some researchers have proposed, using the hot water for bathing, brewing, or hide-working.

This particular site sits to the north-east of Ightermurragh Castle, a proximity that is unlikely to be meaningful in chronological terms since fulachtaí fia are generally prehistoric features, long predating any medieval or early modern structure nearby. The castle and the burnt spread occupy the same landscape but almost certainly belong to entirely different worlds. What connects them is the Womanagh river, running close by to the north, the kind of reliable, accessible water source that made a spot attractive to people across many different periods. The concentration of burnt stone here, still visible as a spread across the tillage ground, is the accumulated residue of that prehistoric use, heat-shattered fragments discarded after each firing.
