It is a limekiln, and while such features are scattered across the Irish countryside in varying states of collapse, this one retains a quiet solidity that makes it worth a second look.

Built sometime in the mid to late nineteenth century, the kiln runs roughly six metres east to west and presents an east-facing front wall of random rubble masonry standing 3.2 metres high and about three metres wide. At its centre is a lintelled recess, a little under 1.7 metres tall and 1.25 metres wide, receding about 1.4 metres into the structure. This opening, known as the draw arch or eye, is where burnt lime would have been raked out after firing. Limekilns like this one were workhorses of the agricultural landscape: local stone rich in calcium carbonate was loaded in from the top along with fuel, burned at high temperature, and the resulting quicklime was spread on acidic fields to improve soil fertility or used as a building mortar. The integration of this kiln into the field boundary itself is typical of the period, when farmers made practical use of existing earthworks rather than building freestanding structures on good agricultural ground.
