The kiln is built against the incline so that limestone and fuel could be loaded from above and the finished product drawn off below, a simple logic that made these structures a fixture of the Irish rural landscape from the seventeenth century onwards.

The construction is compact but considered. Walls of random-rubble sandstone encase the kiln's core, and the northern front elevation features a corbelled recess, a small inward-stepping arch formed by progressively projecting stones, rising to 3.2 metres and capped with a lintel. At the rear, sloping slabs close off the structure, with a small opening at the base. Inside, a stone-lined funnel directed material downward through the burn. The process itself was straightforward: limestone was packed in with layers of fuel, ignited, and left to calcine over many hours. The resulting quicklime was then slaked with water and spread across fields to reduce soil acidity, or used in mortar for building. Kilns like this one were once common enough to be unremarkable; most have since fallen derelict or been absorbed quietly into field boundaries.
