It measures sixteen metres long, thirteen metres wide, and less than a metre high, with its opening facing northwest. Unassuming at ground level, it is in fact a fulacht fia, an ancient cooking site, a type of monument found across Ireland in their thousands. The typical interpretation is that these were places where water was heated by dropping fire-cracked stones into a trough, the shattered and blackened fragments accumulating over repeated use into the characteristic mound that survives today. This particular example is one of at least three clustered within a short distance of each other, which is precisely what makes it worth pausing over.

The proximity of the three sites is striking. A second fulacht fia lies roughly eighty metres to the northwest, and a third approximately sixty metres to the northeast, suggesting that this stretch of ground beside the stream was used repeatedly and perhaps over a long period. The location makes practical sense: a reliable water source was essential for this kind of activity, and the southern side of a stream would have offered reasonable shelter and access. The site was probably among those recorded by Bowman in 1934, who noted fulachta fiadh on land then belonging to a C. Daly, a rare instance of local observation being matched to a specific parcel of ground at a relatively early date for Irish archaeological recording.
