Spread across an area roughly twenty metres by ten, each hollow measures about three metres long and one metre wide, each one rimmed by a low grassy bank. They could be quarry holes. They could be something older and stranger.

The more intriguing possibility is that these are fulachta fia, a type of prehistoric cooking site found widely across Ireland. The basic principle involves heating stones in a fire, dropping them into a water-filled trough to bring it to the boil, and using that heat to cook meat. The troughs, typically timber-lined, leave behind characteristic horseshoe-shaped mounds of burnt and shattered stone, though the shape varies. What makes these Turloughgarve features harder to read is their rectangular form and the fact that they sit within a broader field system rather than in isolation. The persistent wetness of this part of the field is a point in favour of the fulacht fia interpretation, since these sites tend to cluster near natural water sources or areas of poor drainage, which would have supplied the water the process required. But without excavation, the question remains open.
