A fulacht fia is a burnt mound, typically the accumulated debris of a Bronze Age cooking or industrial site, where stones were repeatedly heated in fire and dropped into a water-filled trough to bring it to the boil. They are found in their thousands across Ireland, almost always near water, and this example is no exception. A small stream running in a roughly north-northeast to south-southwest direction cuts through the western edge of the site, and it is there that burnt stones, the telltale signature of the monument type, have been exposed.

The mound is roughly horseshoe-shaped, a form common to fulachta fia, as the crescents of discarded fire-cracked stone tend to build up around three sides of the cooking trough over repeated use. This one measures approximately 6.1 metres east to west and 4 metres north to south, though those dimensions come with an important qualification. The landowner, J. Walsh, noted that the mound had been ploughed some years before it was recorded, reshaping it into its current form. What survives, then, is not quite the monument as it once stood, but a plough-modified remnant, its original profile smoothed and compressed by agricultural work. That kind of quiet disturbance is common enough across the Irish countryside, where prehistoric earthworks and historic field boundaries have long competed for the same ground.
