It is, in all likelihood, a burnt mound, one of the most common yet least-discussed prehistoric monument types in Ireland. These are the accumulated debris of ancient cooking or industrial activity, heaps of fire-cracked stone, charcoal, and dark earth built up over repeated use of a site where water, heat, and stone were brought together, probably by dropping fire-heated rocks into a water-filled trough to boil the contents. Thousands of them survive across the Irish landscape, yet most go unnoticed.

This particular example measures roughly 10.6 metres north to south and 14.4 metres east to west, rising to between half a metre and sixty centimetres in height. Its broadly sloping sides are sod-covered now, but when the mound was inspected in 1998, angular stone fragments, charcoal, and dark soil were visible along its southern and western edges. A slight dip on the south-southwest side, oriented towards an area of wettish ground, may mark the position of a former trough, the functional heart of the site where the actual heating of water would have taken place. The southeastern edge shows a slumped, near-linear scarp, probably the result of disturbance when a field drain was cut approximately two metres away, a drain that has since silted up almost entirely. The mound sits in a natural depression of wet ground, which is typical; proximity to a reliable water source was essential to however these sites were used. Adding an unexpected layer to the immediate landscape, a church and a children's burial ground, the latter being a type of informal cemetery known in Irish tradition as a cillín, lie only around ten metres to the northwest, placing this prehistoric feature in close, if entirely coincidental, company with monuments from much later periods of human activity.
