It appears on an Ordnance Survey map from 1932, marked with enough confidence to be recorded, yet nothing visible survives today to confirm its presence.

A fulacht fia is a type of Bronze Age cooking place found in large numbers across Ireland, typically identified by a horseshoe-shaped mound of burnt and shattered stone beside a trough or pit that would once have been filled with water. The method involved heating stones in a fire and dropping them into the water to bring it to a boil, a technique that leaves behind a distinctive spread of fire-cracked rock. The Killuney example sits in ground that was at some point reclaimed, likely drained bogland or wetland, which is precisely the kind of marginal, water-adjacent terrain where fulachta fia are most commonly found. What makes the site quietly odd is its proximity to a second fulacht fia located just 200 metres to the east-north-east, suggesting that this stretch of north Galway landscape was used repeatedly and perhaps over a long period for the same purpose. That the 1932 map recorded a surface feature that has since vanished entirely, whether through agricultural activity, drainage work, or simple degradation of the mound material, means the site now exists primarily as a cartographic ghost, known through a mark on old paper rather than anything a visitor could stand beside and examine.
