It measures roughly fourteen metres north to south and twelve metres east to west, rising only about sixty centimetres above the surrounding ground. That modest profile, and the burnt material of which it is composed, identify it as a fulacht fia, a type of prehistoric cooking site found in great numbers across Ireland. The basic principle was straightforward: a trough, typically timber-lined or stone-lined, was filled with water, and stones heated in a nearby fire were dropped in to bring the water to a boil. The shattered, fire-cracked stones that accumulated with each use eventually built up into the horseshoe-shaped or oval mounds that survive today, often beside streams or in boggy ground where water was readily available.

The mound at Meenroe shows signs that it has not been left entirely alone. Its surface is notably uneven, and the most likely explanation is that burnt material has been removed at some point, whether for practical use as field drainage or simply cleared away. This kind of disturbance is common at fulacht fia sites, which were rarely recognised for what they were before the twentieth century and were often treated as convenient sources of loose aggregate. The site was recorded in the Archaeological Inventory of County Cork, Volume 4, covering north Cork, published in 2000, which places it among a dense concentration of similar monuments across the county.
