It is a fulacht fia, a type of site found in considerable numbers across Ireland, typically interpreted as an ancient cooking place where water was heated by dropping fire-cracked stones into a trough. Over time, those shattered, heat-spent stones accumulate into the characteristic horseshoe or circular mound that survives in the landscape long after everything else has gone.

This particular example measures roughly 9.7 metres in diameter, with a central depression running approximately 4 metres north to south and 3.3 metres east to west, most likely marking where the original trough or pit was dug. The western side of the mound has suffered some erosion, which is not unusual for sites that have sat in agricultural land for millennia. What makes the location quietly interesting is that it does not stand alone. A second fulacht fia lies approximately 24 metres to the east, suggesting that this corner of Curraleagh saw repeated or sustained use over time, whether by the same community across generations or by different groups drawn to the same patch of ground, possibly because of a nearby water source, which these sites almost invariably required.
