There are no stones jutting through the turf, no obvious sign of construction, just a spread of dark, burnt material beneath the surface. What looks like an ordinary rise in the ground is almost certainly the remains of a fulacht fia, a type of prehistoric cooking site that appears in considerable numbers across Ireland, particularly in low-lying ground near water.

Fulachtaí fia, the plural of the term, are among the most common archaeological monuments on the Irish landscape, though they remain relatively little known outside specialist circles. They typically date from the Bronze Age, roughly 1500 to 500 BC, and follow a consistent pattern: a mound of heat-shattered stone and charcoal, a timber-lined trough, and proximity to a water source. The accepted interpretation is that stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil, cooking meat or perhaps serving other purposes. The broken, fire-cracked stone that accumulated over repeated use formed the characteristic spread that survives today as a mound. At Moskeagh, that mound sits in level pasture with a stream to the west, a configuration that fits the type almost exactly. The stream would have provided the water that was central to the whole process, and the flat ground would have made working around a trough straightforward.
