It measures roughly 5.7 metres across and rises only 0.2 metres above the surrounding ground, modest enough that a walker could easily step over it without a second thought. What lies beneath the grass and encroaching growth is a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically identified by their characteristic mounds of fire-cracked stones and charred material. The standard interpretation is that these sites were used for heating water, either for cooking, bathing, or some other purpose now lost to us, by dropping stones heated in a fire into a water-filled trough until the liquid boiled.

What makes this particular spot quietly interesting is that it does not stand alone. Two further fulachta fiadh lie to the east along the same stream, suggesting that this stretch of waterway was a place people returned to repeatedly, over what may have been a considerable span of prehistoric time. Fulachta fiadh are most commonly dated to the Bronze Age, roughly 2000 to 500 BC, though some have yielded earlier or later dates. The clustering of three sites along a single stream at Currahaly points to something purposeful in the choice of location, where proximity to running water and the soft, marshy ground were likely practical requirements rather than coincidences of survival.
