This is a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically identified by the scorched, crumbled stone that accumulates when rocks are repeatedly heated and plunged into water-filled troughs. The mound here measures roughly seven metres along its longer axis and just under half a metre in height, dimensions that are fairly typical of the form.

What makes the Urraghilmore site quietly interesting is not the mound itself in isolation but the fact that a second fulacht fia lies only about 130 metres to the south-west. The proximity of two such sites suggests repeated or sustained activity in this particular part of the landscape, probably drawing on the same nearby stream as a water source. Fulachtaí fia, as the plural form goes in Irish, date broadly to the Bronze Age, though some examples span a wider range, and their exact purpose has been debated for decades. Boiling meat is the most commonly cited explanation, but brewing, hide-working, and bathing have all been proposed as alternatives, and the honest answer is that the function may well have varied from site to site and period to period.
