It is a lime kiln, a structure type that was once so commonplace across the Irish countryside as to be almost invisible, yet which represented a critical piece of agricultural technology. By burning limestone at high temperatures, farmers produced quicklime, which they then spread across acidic soils to improve fertility. The kilns fell out of use as industrially produced lime became widely available, and many have since crumbled or been absorbed into field boundaries. This one, at four metres square, survives in reasonable definition.

The structure follows the form typical of field or roadside kilns. The front face carries a rectangular recess opening, roughly a metre wide and just over a metre tall, through which the burnt lime would have been raked out from the base of the fire. A horizontal ledge runs across the face at around three metres above ground level, and above that the funnel, two metres in diameter, narrows as it descends, channelling the charge of limestone and fuel downward toward the burning chamber. The whole front wall is of random rubble construction, meaning the stones are laid without any attempt at coursing or uniformity, a practical and entirely typical approach for rural industrial structures of this kind. The recess opening is partly obscured by a gravel dump, which has accumulated against the base of the wall over time, softening the lower details of the structure without hiding the overall form.
