It measures roughly 8.7 metres along its northwest to southeast axis and 6.4 metres across, rising to a height of just 0.2 metres, with a slight depression at its centre. To a casual eye it reads as nothing more than a boggy rise in a wet field. In fact it is a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, and this particular example is one of a cluster of five within the same immediate area.

Fulachta fiadh are among the most common archaeological monuments in the Irish landscape. The typical interpretation is that they represent outdoor cooking places, used during the Bronze Age, where water was heated by dropping fire-cracked stones into a trough. Those shattered, heat-spent stones were then discarded in a horseshoe or crescent-shaped mound around the trough, which is precisely what gives sites like this one their characteristic form and their scorched, dark-coloured fill. The slight central hollow visible here likely marks where the original trough sat. The marshy, streamside location is entirely typical; access to water was fundamental to how these sites functioned. What makes Kilcolman worth noting is the concentration of five such monuments in close proximity, suggesting repeated or sustained activity in this particular stretch of the Cork countryside rather than a single isolated episode.
