It is a lime kiln, the kind of utilitarian landmark that once punctuated the Irish countryside with quiet regularity before agricultural chemistry rendered it redundant. A lime kiln was used to burn limestone at high temperatures, producing quicklime that farmers spread on acidic soils to improve their yield. Most have crumbled, been absorbed into field boundaries, or simply been forgotten. This one survives with enough structural integrity to still read as a building.

The kiln faces south-west, and its front elevation retains a flat segmental-arched recess, roughly 1.7 metres high and 1.8 metres wide, with a second, lower arch set within it leading further inside. That double-arch arrangement is typical of the form: the outer recess sheltered the draw hole where burnt lime was raked out, while the inner arch gave access to the bowl above where the fuel and limestone were loaded and fired. The sandstone construction places it within a broader regional tradition of using whatever local material lay closest to hand, dressed only as much as the task required.
