To the untrained eye it reads as nothing more than a slight rise in the ground, but beneath the grass lies a spread of burnt material measuring roughly 12 metres by 21 metres. It is a fulacht fia, and its location beside water is entirely deliberate.

Fulachtaí fia are among the most common prehistoric monument types in Ireland. They are typically interpreted as outdoor cooking sites, the working principle being straightforward: stones were heated in a fire and then dropped into a water-filled trough, bringing the water to a boil quickly enough to cook meat. The crescent or horseshoe-shaped mounds that mark them today are the accumulated debris of that process, the cracked and shattered stones discarded after use over many episodes, sometimes spanning centuries. The proximity to a natural spring or stream was essential, providing a ready water source. What makes the Curraghnalaght site quietly notable is that it does not stand alone. A second fulacht fia lies just 16 metres to the west, suggesting this particular patch of ground, with its reliable spring, drew repeated or concurrent use.
