Lime kilns were once a familiar feature of the Irish agricultural landscape, used to burn limestone at high temperatures to produce quicklime, which farmers then spread on acidic soils to improve fertility. Most have crumbled or been absorbed into field boundaries, which makes a surviving example of this scale, standing over three metres high and nearly four and a half metres wide across the front, quietly notable.

The structure is built from random rubble, a term describing stonework laid without regular courses, with the outer wall acting as a shell that retains an earthen core behind it. The overall footprint runs approximately four and a half metres on the northeast to southwest axis and six metres on the northwest to southeast, giving it a solidity that has helped it endure. The front elevation faces southeast, and within it sits an arched recess just under three metres wide, which would originally have allowed access to the draw hole at the base, where burnt lime was raked out after firing. At the rear, a steep scarp about a metre high marks where a loading ramp once stood; the ramp itself has been removed, leaving the circular stone-lined funnel at the top of the kiln, into which limestone and fuel were fed, now accessible only with some effort.
