Roughly circular, measuring about 6.6 metres east to west and 6.4 metres north to south, it rises only around 10 centimetres above the surrounding ground. Beneath the turf, however, the mound is composed of heat-shattered stones and charcoal-enriched soil, the signature materials of what archaeologists call a burnt mound.

Burnt mounds are among the most widespread prehistoric monument types in Ireland, found in their thousands across the country, yet they remain genuinely puzzling. The working theory is that they represent the accumulated debris of a cooking method: stones were heated in a fire, then dropped into a water-filled trough to bring it to the boil, and the cracked, spent stones were discarded to form a mound over time. Some researchers have proposed alternative uses, including sweat-house bathing or industrial processes, but no single explanation covers every example. The Teeveeny mound fits the classic profile precisely, its modest height and circular form typical of the type, and the charcoal-enriched soil pointing clearly to repeated burning over what may have been a prolonged period of use during the Bronze Age.
