Measuring roughly 2.8 metres north to south and less than 2 metres across, it rises only 45 centimetres above the surrounding rough hill pasture. What makes it worth attention is what the eroding riverbank exposes: heat-shattered stones and charcoal-enriched soil, the unmistakable signature of prehistoric cooking activity.

This is a burnt mound, the result of a process practised widely across Ireland during the Bronze Age. The typical method involved heating stones in a fire, then dropping them into a water-filled trough to bring the water to a boil, used for cooking or possibly other purposes such as bathing or hide-working. The discarded, cracked stones accumulated over repeated use into the low, rounded mounds that still dot the Irish landscape in their thousands. What makes this particular site slightly unusual is its proximity to a second feature: a fulacht fia, the Irish term for this same class of monument, lies roughly 10 metres to the south-east on the opposite bank of the same stream. A fulacht fia typically refers to the broader cooking site, including any associated trough or hearth, while a burnt mound describes the spoil heap itself. Having both recorded so close together, separated only by a narrow watercourse, suggests a small area of repeated, perhaps sustained, prehistoric use on this quiet hillside above Ardgroom.
