A lime kiln is a relatively simple industrial structure, typically used to burn limestone at high temperatures to produce quicklime, which farmers spread on fields to reduce soil acidity. This one is modest in scale, with an arched recess measuring roughly 1.6 metres high, 3.78 metres wide, and about 2 metres deep, fronted by a lower inner arch. The rubble that has gathered around the opening obscures part of it, and the whole structure has the quality of something slowly being reclaimed by the ground it was built into.

The kiln appears on the Ordnance Survey six-inch map of 1842, which places it firmly in the pre-Famine landscape, a period when lime-burning was a routine part of agricultural improvement across rural Ireland. Landowners and tenants alike relied on locally produced quicklime to condition boggy or acidic soils, and kilns of this kind were often built close to roads for ease of fuel and limestone delivery. This particular example was repaired in the early 1990s, which likely accounts for at least some of its surviving structural coherence. More recently, roadworks in the area exposed the earthen core of the kiln on its southern side, offering an unintended cross-section of how these structures were constructed, a rubble or stone outer shell packed around a compacted earthen interior designed to retain the enormous heat of a burn.
