This is a fulacht fia, a type of prehistoric cooking site found in extraordinary numbers across Ireland, typically dating to the Bronze Age. 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 heat to cook meat. What remains after centuries is usually the mound itself, composed of the fire-cracked, burnt stones discarded after each use. Here, that mound measures 13.4 metres in length, 6.3 metres in width, and just 0.55 metres in height, with a four-metre opening facing north.

The site sits on marshy ground to the south of the surrounding pasture, which is typical. Fulachtaí fia are almost always found near a reliable water source, and low-lying, wet ground provided exactly that. The mound at Meenroe has not been entirely untouched; local information indicates that burnt material was spread to the north by ploughing at some point, which means the original extent of the deposit was likely greater than what is visible today. What makes this particular location quietly notable is that it does not stand alone. A second fulacht fia lies roughly 50 metres to the northwest, suggesting that this corner of north Cork saw repeated, perhaps sustained, prehistoric activity rather than a single isolated episode of use.
