The place in question is a fulacht fia, a type of ancient cooking or industrial site found in enormous numbers across Ireland, typically identified by a distinctive mound of fire-cracked stones and charcoal left behind when heated rocks were repeatedly plunged into water-filled troughs. At Templenacarriga, even that trace is gone.

When the land was reclaimed for agricultural use, burnt material consistent with a fulacht fia was uncovered and subsequently removed. No excavation appears to have taken place, and no visible surface feature remains. What survives is little more than a local memory of the discovery, passed on informally rather than captured through any formal investigation. Fulachtaí fia are generally associated with prehistoric activity, most commonly the Bronze Age, though their precise function is still debated; some archaeologists favour cooking, others suggest hide-working, brewing, or bathing. Whatever was happening at Templenacarriga, the physical evidence for it has been scattered into the field margins or carted away entirely, leaving only the coordinates and a note that something was once there.
