Inside the Hoffmann Kiln, Langcliffe, North Yorkshire.
The kiln was built in 1873 at the old Craven Limeworks from a German design for the continuous burning of lime to make slake lime. The arched chambers were divided into sections which were stacked with blocks of limestone. Coal was dropped through holes in the roof and the fire moved from chamber to chamber in a six week cycle. The kiln was closed in 1939 and the chimney has since been demolished. This is the best example of a Hoffmann Kiln in the country.
