It measures roughly six metres by four, rises less than a metre above the surrounding ground, and is composed almost entirely of burnt material. Blanket bog presses in around it on all sides, and a small stream flows north-westward just a couple of metres to the south. Nothing about it announces itself, yet it represents one of the most common and most intriguing categories of prehistoric monument in Ireland.

This is a fulacht fia, a type of ancient cooking or processing site found in enormous numbers across the Irish landscape, with many thousands recorded to date. The typical arrangement involves a hearth, a timber-lined trough filled with water, and a working area nearby. Stones were heated in the fire and dropped into the trough to bring the water to a boil, then discarded once they cracked and became unusable. Over time, the shattered, fire-reddened stones accumulated into the horseshoe-shaped or oval mounds that survive today, often dark and peaty in composition. Most date to the Bronze Age, broadly spanning the period from around 2500 to 500 BC, though some sites have produced earlier or later dates. The proximity of this example to a stream fits the pattern well; a reliable water source was essential to the whole operation, and fulachta fiadh are almost invariably found close to one.
