Lime kiln near St Simon’s Chapel
Description

Lime kiln near St Simon’s Chapel MYD34521 (c) YDNPA, 2023
This lime kiln is sited close to the Medieval St Simon’s Chapel. It is circular in plan with a segmental arch above the draw hole opening. The lime kiln is unusual in having traces of a date, possibly 1786, roughly inscribed on the east springer of the draw hole opening.
Field lime kilns such as this one were built to burn limestone. The quicklime produced was then slaked with water to produce calcium hydroxide (slaked lime). This was mostly used to improve grassland by reducing the acidity of the soil, especially of intake land or reclaimed moorland during the enclosures of the 18th and 19th centuries. Slaked lime was also an important ingredient in making lime mortar.
