The mound is the remains of a fulacht fia, a type of prehistoric cooking site found widely across Ireland, typically associated with the Bronze Age. The method involved heating stones in a fire, dropping them into a water-filled trough to bring it rapidly to the boil, and using the heated water to cook meat. Repeated heating and cooling caused the stones to fragment, and over time the discarded cracked material accumulated into the distinctive crescent-shaped mounds that survive today. This particular example is a substantial one, measuring roughly 20.8 metres east to west and 17.8 metres north to south, with a maximum height of 1.8 metres. Between its two arms sits an additional deposit of burnt stone, creating what amounts to an almost enclosed trough area of around 6.6 by 6.5 metres open only to the north-west.

What makes this site quietly striking is not the mound itself but its setting and its company. The slope it occupies is fed by numerous small spring wells emerging from the outcropping rock, which would have made it an obvious choice for repeated use; a ready water supply was essential to the fulacht fia process. The site was recorded as a small mound on Ordnance Survey six-inch maps from both 1842 and 1915, though it was classified only as a vague "Earthwork" in heritage records from 1992 and 1996, its true character apparently unrecognised at those points. More telling still is the clustering of similar monuments nearby. Two further burnt mounds lie within 20 metres to the west and north-west, and another fulacht fia sits just 50 metres to the north. This concentration suggests the area was not visited once and abandoned, but returned to across time, perhaps by communities who understood the value of a reliable spring on sheltered ground.
