This is a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically dating from the Bronze Age. The standard interpretation is that stones were heated in a fire, then dropped into a water-filled trough to bring it rapidly to a boil, the discarded cracked stones accumulating over time into the characteristic low, horseshoe-shaped mound that survives today. The Kilbane example measures 7.5 metres long, 6.7 metres wide, and stands roughly a metre high, with a western-facing opening some 4 metres across.

What makes this particular site quietly interesting is not the mound itself but its company. Within roughly 60 to 80 metres to the east lie two further fulachta fiadh, making this a cluster of three related sites in close proximity. Whether they represent repeated use of a favoured spot over generations, or activity by a community that habitually returned to the same stretch of stream and marshy ground, is impossible to say with certainty. But the grouping is a reminder that these sites, often treated as solitary curiosities, were sometimes part of a denser pattern of prehistoric activity tied to water sources and low-lying wet terrain.
