What lies beneath is the remains of a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, and one of the most quietly persistent features of the Irish landscape. The grass has long since reclaimed the surface, leaving little visible to the casual eye beyond a gentle rise in the field.

Fulachtaí fia, sometimes translated loosely as "deer roasts", are typically Bronze Age in date, though examples span a wide chronological range. The basic principle involved heating stones in a fire, dropping them into a water-filled trough to bring it to a boil, and using that trough to cook meat or, as some researchers now argue, for a range of other purposes including textile processing or even brewing. The burnt and shattered stones, discarded after each use, accumulated over time into the horseshoe-shaped or spread mounds that survive today. The proximity to a stream is entirely characteristic; a ready water supply was essential to the process, and it is rare to find a fulacht fia far from running water. The example at Seeds follows this pattern precisely, sitting close to the eastern bank of its unnamed watercourse in the North Cork countryside.
