⛏ Harpur Hill Quarry

Harpur Hill Quarry is a disused limestone quarry on Harpur Hill, Derbyshire, England. Limestone was extracted there from 1835 to 1952 for lime burning at lime kilns to produce quicklime. The quarry was used by the Royal Air Force as a chemical weapons storage depot during the Second World War, the largest such depot in the United Kingdom. Afterwards a number of captured German chemical munitions were disposed of at the site by burning, which was only partially successful. The RAF depot closed in 1960 and the site is now vacant.
