Its front face rises to around ten metres, and at its base sits an arched recess, just over two metres high and wide, formed from cut stone voussoirs, the wedge-shaped blocks used to construct a stable arch. Behind the arch, sloping slabs lead inward, and above sits a stone-lined funnel roughly two metres in diameter. The rear of the structure is enclosed by a wall, and the top has long since been claimed by vegetation.

Lime kilns like this one were once a familiar feature of the Irish agricultural landscape, used to burn limestone at high temperatures and produce quicklime, which farmers spread on acidic soils to improve their fertility. They were also used in the production of mortar for building. The process required a continuous supply of fuel and stone, and kilns were typically built into natural slopes precisely as this one is, allowing material to be loaded from the top while the burnt lime was drawn out through the arched recess at the front. The careful stonework here, particularly the voussoirs of the arch, suggests this was a well-constructed example rather than a purely functional field structure thrown together in haste.
