This one in Booladurragha, County Cork, leaves no mark at all above ground, and its existence is known almost entirely because a farmer turned it up during land reclamation work around 1980. What came to light was burnt material, the characteristic signature of a fulacht fia, an ancient cooking site typically consisting of a mound of fire-cracked stones accumulated over repeated use. The process involved heating stones in a fire and dropping them into a water-filled trough to bring the water to a boil; the cracked and spent stones were raked aside after each use, gradually forming the horseshoe-shaped mounds that survive across the Irish landscape in the thousands. Before the reclamation disturbed the ground here, there was not even a mound to hint at what lay beneath.

The site sits in tillage land, roughly 170 metres north-east of a separate fulacht fia, suggesting this part of Cork saw repeated or sustained activity of this kind at some point in prehistory, most likely during the Bronze Age, when fulachtaí fia were in widespread use. The proximity of two such sites is a reminder that what looks like empty farmland has often been shaped by long cycles of human activity, most of it now invisible without excavation or accidental disturbance. In this case, the land reclamation that destroyed the archaeological context was also the only reason the site came to be recorded at all. There is now no visible trace of burnt material remaining.
