It measures eighteen metres long and twelve metres wide, irregular in outline, and composed almost entirely of burnt material. This is a fulacht fia, a type of prehistoric cooking site found in great numbers across Ireland, typically Bronze Age in origin. The usual interpretation is that stones were heated in a fire and then dropped into a water-filled trough to bring it to boiling point, the cracked and discarded stones accumulating over repeated use into exactly the kind of horseshoe-shaped or irregular mound visible here.

What makes this particular site quietly remarkable is not the mound itself but its company. It is one of a cluster of five fulachta fiadh recorded in the Flemingstown area, sitting in close proximity to one another in the same reclaimed ground. The concentration of sites suggests sustained, repeated activity in this landscape over time, possibly drawing on a reliable water source nearby, since a ready supply of water was essential to the whole process. Clusters like this are known elsewhere in Ireland and continue to prompt debate among archaeologists about whether these sites represent seasonal gatherings, communal food preparation, or something else entirely.
