The one at Urraghilmore in County Cork is a quiet example of a structure type that once shaped the agricultural landscape far more than its modest appearance suggests. A lime kiln was essentially a stone furnace, typically built into a hillside or bank, in which limestone was burned at high temperature to produce quicklime. Farmers spread the resulting material across acidic soils to improve fertility, and its use was widespread from at least the eighteenth century through to the early twentieth, when cheaper alternatives gradually made local burning redundant.

The kilns left behind are often mistaken for collapsed field walls or natural rock formations, which goes some way to explaining why they attract so little attention. In townlands like Urraghilmore, where the land retains the texture of older agricultural practice, these structures are a physical record of how communities managed the soil before industrialised inputs arrived. The labour involved was considerable: limestone had to be quarried or carted, fuel gathered, and the burn maintained over many hours before usable lime could be extracted from the draw hole at the base.
