A lime kiln is a structure used to burn limestone at high temperatures to produce quicklime, a material essential for mortar, whitewash, and soil improvement on farmland, and examples like this one were once commonplace features of the rural Irish landscape. What makes this particular structure worth pausing over is the material from which it was built: conglomerate stone, a sedimentary rock composed of rounded fragments cemented together, giving the masonry a distinctly coarse and varied texture that sets it apart from the more uniform stonework of many similar kilns.

The kiln measures roughly three metres in height and just under six metres in width, constructed directly against a slope, a typical arrangement that allowed workers to load limestone and fuel from above while the fired lime was drawn out through the arched opening at the front. The front and south-western side walls retain an earthen core, and the recess itself, at nearly two and a half metres deep, has sloping slabs at the rear and curved side walls, details that speak to a considered, if vernacular, approach to construction. The rear of the structure is now inaccessible, obscured entirely by overgrowth, leaving only the south-eastern elevation fully readable.
