Roughly square in plan and dating from the mid to late nineteenth century, it is a lime kiln, the kind of industrial remnant that once shaped the agricultural landscape across rural Ireland as thoroughly as any field boundary or farmhouse. A lime kiln was essentially a furnace for burning limestone, producing quicklime that farmers spread across acidic land to improve its fertility. They were commonplace enough in their day that most have since collapsed, been absorbed into walls, or simply gone unnoticed.

This one survives with some architectural coherence. The front elevation, facing south, measures roughly 3.4 metres high and 3.8 metres wide, and features a lintelled recess, that is, an opening spanned by a horizontal stone rather than an arch, just over a metre wide and nearly two metres deep. Immediately inside the lintel, sloping slabs direct downward into the kiln's interior. Above and beyond them, the funnel, the tapering shaft through which the charge of limestone and fuel would have been loaded from the top, remains visible but is no longer accessible. It is a compact, purposeful piece of vernacular engineering, and the proportions of that front recess, where workers would have drawn out the burnt lime, give some sense of the physical scale of the labour involved.
