The example at Tooreenduff in County Cork is one such survival, recorded as a monument but otherwise undocumented in the public domain for the time being.

Lime kilns were used to burn limestone at high temperatures, producing quicklime that farmers spread across acidic soils to improve fertility. The practice was widespread from at least the seventeenth century onwards and continued in parts of rural Ireland well into the twentieth. A kiln typically consists of a stone-built bowl or pot set into a hillside or earthen bank, with a draw arch at the base through which the burnt lime could be raked out. Fuel, usually turf or coal, was layered with the limestone and kept burning for days at a time. The resulting quicklime was caustic and had to be handled carefully, often slaked with water before use. The presence of a kiln in Tooreenduff speaks to the same agricultural realities that shaped townlands across Munster, where improving the land was a constant and labour-intensive concern.
