This is a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland. The characteristic shape comes from the gradual accumulation of fire-cracked stone, discarded after each use into a crescent-shaped midden around a central trough. The process was straightforward: stones were heated in a fire, dropped into a water-filled pit to bring it rapidly to the boil, and used to cook meat. Repeated over time, this produced the distinctive mounds that survive today, often on low-lying or marshy ground where water was close to the surface.

The site was recorded by Bowman in 1934, and the burnt material that typically characterises such monuments, the shattered, fire-reddened stone that gives fulachta fia their telltale colouring, was not positively identified at the time of survey. That absence of confirmed burnt stone is a small puzzle; it may reflect the condition of the mound, the extent of the survey, or simply the passage of time and agricultural disturbance. Fulachta fia are generally dated to the Bronze Age, roughly 1500 to 500 BC, though some have produced earlier or later dates. They are among the most common prehistoric monument types in Ireland, yet individual examples like this one, sitting unmarked in ordinary farmland, rarely receive much attention.
