It is a lime kiln, the kind of industrial remnant that once defined agricultural landscapes across Ireland, and this one retains enough of its original fabric to give a clear sense of how it worked. Lime kilns were used to burn limestone at high temperatures, producing quicklime that farmers spread on acidic soils to improve fertility. They were functional, local, and largely unremarked upon, which is perhaps why so many have quietly survived.

The kiln is east-facing, with a front wall stretching just over three metres wide. At its centre is a blocked stone-arched recess, two metres high and spanning the full width of the wall, with a small rectangular opening at its base that once gave access to the funnel inside. That funnel, stone-lined and barrel-shaped in cross-section, measures nearly four and a half metres in diameter. A ramp on the southern side would have allowed workers or animals to bring fuel and limestone to the top, where the raw materials were loaded in from above, while the burnt lime was raked out through the opening below. The projecting end walls are a typical feature of the type, providing structural stability and framing the draw arch. The setting, on a working estate beside a river, is consistent with the kind of integrated rural economy in which such kilns were essential infrastructure rather than curiosities.
