Built into a steep bank on the north side of the road, its rubble front wall stands three metres high and two and a half metres wide, facing south, and has been folded into the line of an adjacent field boundary. The central recess, just under two metres tall and roughly a metre and a half wide, is spanned by a rough arch built without voussoirs, meaning the stones were laid without the shaped, wedge-cut blocks that would normally lock a classical arch together. The whole upper section is now overgrown.

Lime kilns like this one were once a familiar presence across rural Ireland. Farmers used them to burn limestone at high temperatures, producing quicklime that could then be spread on acidic soil to improve its fertility, or mixed with water and sand to make mortar. The construction here is modest and functional, around four metres in length from north to south, built from random rubble rather than dressed stone. That rough arch, holding its shape without formal voussoirs, is a small curiosity in itself, evidence of a practical vernacular tradition where the goal was a working structure rather than an engineered one. By the time this kiln was built, in the latter half of the nineteenth century, agricultural improvement schemes had made lime burning widespread across Kerry, though the industry faded as commercially produced lime became more accessible.
