A burnt mound is exactly what the name suggests: a low accumulation of fire-cracked stone and charcoal-dark soil, the waste heap left behind by a Bronze Age practice of heating stones in a fire, then dropping them into a water-filled trough to bring it to the boil. Thousands of these monuments survive across Ireland, many of them clustered near former wetlands, and this one is no exception.

Before the land around it was drained and reclaimed for agriculture, the site sat beside a natural depression roughly thirty metres across that would have been wet and marshy, exactly the kind of waterlogged hollow that made such a location practical for repeated heating and cooking. The mound itself was originally a small, low, roughly semi-circular grass-covered rise, and in front of it there were stones apparently defining a shallow hollow, most likely the remnant of the trough into which the heated stones were dropped. Land reclamation levelled the mound entirely, and the disturbance exposed a concentration of angular stone fragments in greasy black soil spanning about ten metres in diameter. When the site was inspected in 1996, there was nothing visible at ground level; only probing beneath the turf confirmed that the burnt stone and dark, organic-rich soil were still there, compressed and hidden but intact. A farm track now runs immediately to the north-west of the spot.

There is nothing to see here in any conventional sense, and that is precisely what makes the site quietly interesting. The reclamation that erased the mound also, in an indirect way, preserved the subsurface deposit by compacting and covering it. What was once a small but legible prehistoric monument is now a kind of invisible archive, sealed under grass, confirmed by a probe rather than by any visible feature.
