It measures roughly eight metres by six, and rises only about twenty centimetres above the surrounding ground. To a casual eye it might register as nothing more than a slight rise in the earth, perhaps a trick of the terrain. But the material beneath the grass cover tells a different story: heat-shattered stones and charcoal-enriched soil, the characteristic signature of a burnt mound.

Burnt mounds, known in Irish archaeology as fulachtaí fia, are among the most common prehistoric monument types found across Ireland, yet they remain largely unfamiliar outside specialist circles. The working theory, broadly accepted though still debated, is that they functioned as cooking sites. Stones would be heated in a fire and dropped into a water-filled trough to bring it to a boil, shattering in the process. Over repeated use, the broken, fire-cracked stones accumulated into a mound beside the trough, often crescent-shaped or oval in plan. The charcoal-rich soil at Teeveeny fits this picture precisely. A drain cuts across the western edge of the mound, truncating it slightly, which suggests the landscape has been worked and managed in later periods without whoever did so necessarily recognising what the mound was.
