The burnt mound at Reenturk, in County Kerry, does none of that. It has no visible surface presence at all, which makes it, in a quiet way, an oddity even among its own kind.

Burnt mounds are among the most common prehistoric monuments in Ireland, low spreads of heat-shattered stone and charcoal-blackened soil that accumulated wherever people repeatedly heated stones in fire and then dropped them into water-filled troughs, probably for cooking, bathing, or industrial processes. Most do leave a visible hump in the ground. Here, the evidence survived only as a buried layer of burnt soil and stone, exposed in the north face of a drainage channel cut through a field at Reenturk. That layer extended across just over three metres in section. The south face of the same drain showed nothing, and investigation of nearby drains found no continuation of the burning. What survives is, in effect, a cross-section through a past event, preserved underground and only glimpsed by accident when the drain was cut.
