Lime kilns were once a familiar feature of the Irish agricultural landscape, used to burn limestone at high temperatures to produce quicklime, which farmers spread on acidic soils to improve fertility. Most have collapsed or been absorbed into field boundaries over the centuries, which makes a relatively intact example like this one quietly notable.

The kiln faces west, its front wall constructed in random rubble, meaning irregularly shaped stones laid without formal coursing. At ground level, an arched recess opens into the structure, measuring roughly 1.73 metres high, 1.55 metres wide, and 1.35 metres deep, with sloping slabs set into the rear. This was the eye of the kiln, where fuel was fed in and the burnt lime eventually extracted. A horizontal ledge runs across the front face at about 2.1 metres above the ground, and the side walls are also roughly built in random rubble. The top of the kiln, where limestone would have been loaded into the funnel-shaped chamber from above, is accessible from the avenue itself, the slope allowing that upper access without any need for ladders or ramps. The funnel is now largely infilled, which is common in disused kilns, where the chamber gradually accumulates debris once the structure falls out of regular use.
