It measures roughly five metres east to west and six metres along its straight western side, rising only about forty centimetres from the surrounding ground. What makes it worth pausing over is what lies beneath that uneven turf: a dense accumulation of heat-shattered stones and charcoal-enriched soil, the signature remains of a burnt mound.

Burnt mounds are among the most widespread yet least-celebrated monument types in the Irish landscape. They are generally understood as the debris of a cooking or heating process used during the Bronze Age, in which stones were repeatedly heated in fire and then plunged into water-filled troughs to bring the water to a boil, cracking and shattering the stones in the process. Over time, the spent, fractured stones and ash were raked aside into a crescentic or D-shaped heap beside the water source. The classic D-shape of this particular mound, with its flat side facing the stream, fits that pattern precisely. Hundreds of such features survive across Ireland, often in boggy ground where the acidic, waterlogged conditions have helped preserve both the mound material and, in some cases, the wooden troughs beneath. The stream beside this example and the old field boundary wall running along its opposite bank suggest a landscape that has been in continuous, quiet use across a very long stretch of time.
