Roughly horseshoe-shaped and measuring thirteen metres north to south and fourteen metres east to west, it rises only half a metre above the surrounding land. That modest height is deceptive. The mound is a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically dated to the Bronze Age. The usual interpretation is that stones were heated in a fire, then dropped into a water-filled trough to bring the water rapidly to the boil. Over repeated use, the stones cracked and became useless, and the accumulated debris of burnt, fragmented rock was raked away to form the characteristic crescent or horseshoe shape that survives today.

What makes this particular example worth pausing over is the physical detail still visible in the mound itself. Large boulders protrude from the surface in the north-western sector, and upright stone slabs, known as orthostats, can be seen emerging from the south-western face. These orthostats may mark the location of the original trough, the stone-lined pit or wooden container into which the heated rocks were plunged. The site does not stand alone. Two further fulachtaí fia lie roughly sixty metres to the south-west, suggesting that this stretch of poorly drained ground at the edge of the bog was used repeatedly, perhaps by different groups or across different generations. Waterlogged land of this kind was ideal: a ready water supply, and ground that held moisture even in dry seasons. The clustering of three sites in close proximity is a reminder that these features, though often treated as isolated curiosities, were part of a much broader pattern of organised activity in the prehistoric landscape.
