A fulacht fia, to give it its Irish name, is a type of ancient outdoor cooking place found in enormous numbers across Ireland, typically consisting of a trough filled with water that was heated by dropping fire-cracked stones into it. The stones, once spent, were piled nearby, forming a horseshoe-shaped mound of dark, fire-shattered material. It is that spread of burnt stone and charcoal that marks this particular site, detectable in the soil even after the mound itself has been lost.

The earthwork here was levelled during drainage works around 1982, according to research published by Walsh in 1985. What survived was the scatter of burnt material beneath, visible for a time when the field was ploughed, before the land returned to pasture managed for silage. The site sits on the eastern side of a stream, which is exactly where these features tend to cluster, since a reliable water source was essential to their function. That same stream corridor carries at least three other fulachta fia in close proximity, one further downstream to the north-west and two more upstream, suggesting this was a stretch of ground returned to repeatedly, perhaps seasonally, over a long period of prehistoric use.
