At just twelve centimetres high and roughly twenty-two metres across at its longest point, it would be easy to mistake for a natural irregularity in the ground, perhaps a slight rise left by old drainage work. In fact, it is the remains of a fulacht fia, a class of prehistoric cooking site found in extraordinary numbers across Ireland, typically beside water sources and dating most commonly to the Bronze Age. The usual interpretation is that stones were heated in a fire, then dropped into a water-filled trough to bring it to the boil, with the cracked and shattered residue piling up over repeated use into the characteristic horseshoe-shaped mound that survives at so many sites. Here, a modern agricultural drain cuts through the southern end, and the mound itself is irregular rather than the more textbook horseshoe form.

The site sits in ground that has seen some land reclamation for tillage, which partly explains its worn-down condition. A researcher named Bowman documented what may be this same feature, referencing it in relation to land then belonging to a M. Bourke, though whether the two records describe identical ground is not entirely certain. That kind of ambiguity is not unusual with fulachtaí fia; they were rarely the subject of close attention until relatively recently, and many were recorded informally, or described in passing in older county surveys, before systematic archaeological inventory work gave them more precise coordinates and measurements.
