Somewhere beneath the surface of a field on the north bank of a stream in County Cork lies what was once a fulacht fia, a type of ancient cooking site found in enormous numbers across Ireland, typically identified by a mound of fire-cracked stones and charred earth left behind after repeated use. At Rooskagh, even that modest outline has gone. The ground gives nothing away.

What little is known comes from a single moment of accidental discovery. Around 1981, land reclamation works disturbed the north bank of a local stream and brought up burnt material, the charred residue that typically accumulates at a fulacht fia where stones were heated in fire and plunged into a water-filled trough to bring it to the boil. The find was recorded on the basis of local information rather than formal excavation, which means the full extent of the site, and any finer detail about its age or use, remains unknown. Fulachtaí fia are generally associated with the Bronze Age, roughly 2000 to 500 BC, though some span earlier or later periods, and they appear most often close to water sources, exactly the kind of streamside location described here. Without excavation, Rooskagh keeps its particulars to itself.
