The site is a fulacht fia, a type of prehistoric cooking place found in large numbers across Ireland, typically identified by a horseshoe-shaped mound of burnt and shattered stone beside a stream or marshy hollow. The usual interpretation is that stones were heated in a fire, dropped into a water-filled trough to bring it to the boil, and used for cooking meat. They are among the most commonly recorded prehistoric monuments in Ireland, yet individual examples disappear with quiet regularity.

This particular fulacht fia appeared on the Ordnance Survey six-inch map of 1938, marked on the eastern side of a local stream. By the time anyone came to look for it on the ground, the area had been flooded by an artificial lake created in connection with sand and gravel extraction. Two neighbouring fulachta fiadh in the same townland met the same fate. All three sites, recorded on paper but no longer accessible beneath the water, represent a small but telling loss: a cluster of prehistoric activity that once suggested repeated or sustained use of this stretch of landscape, now submerged under industrial workings.
