It is roughly circular, measuring just over thirteen metres east to west and twelve metres north to south, and rises only half a metre from the surrounding ground. Nothing about it would catch the casual eye, yet what lies beneath the turf is a record of prehistoric activity that archaeologists recognise across Ireland and Britain: a burnt mound, or fulacht fiadh, composed of heat-shattered stones and charcoal-enriched soil.

Burnt mounds are among the most commonly found prehistoric monuments in Ireland, yet their precise purpose has been debated for generations. The most widely accepted interpretation is that they were cooking sites. Stones would be heated in a fire and then dropped into a water-filled trough to bring the water to boiling point, a method that leaves behind exactly the kind of cracked, fire-fractured stone that characterises these mounds. Other theories propose use for brewing, hide-working, or bathing. Whatever their function, they tend to cluster near water sources and on sheltered slopes, and the Teeveeny example fits that pattern well. The mound has not escaped entirely unscathed; drainage works have cut into both its eastern and western edges, truncating what would once have been a more complete profile.
