It is a fulacht fia, a type of ancient cooking site found in enormous numbers throughout Ireland, typically dating from the Bronze Age. The usual interpretation is that these sites were used for boiling water by heating stones in a fire and dropping them into a water-filled trough; the crescent-shaped or horseshoe mounds that survive today are the accumulated debris of cracked and spent stones, built up over repeated use.

What makes this particular mound worth noting is that it does not stand alone. It belongs to a cluster of four fulachta fiadh recorded in the same general area, which points to this stretch of boggy ground being returned to, perhaps seasonally, over an extended period. The consistent association of these sites with streams and wet ground is well established; ready access to water was essential to the whole process. The proximity of this group to one another raises quiet questions about how the landscape was used, and by whom, and whether the gatherings they imply were practical, social, or something harder to categorise from this distance in time.
