Chislehurst Caves

About

The Chislehurst Caves are a series of intersecting man-made tunnels and caverns covering some 22 miles (35.4 km) in Chislehurst in the London Borough of Bromley.

Today the caves are a tourist attraction and, although they are called caves, they are entirely man-made and were dug and used as chalk and flint mines. The earliest recorded mention of the mines and lime-burning kilns above dates from a 9th-century Saxon charter and then not again until around 1232AD; they are believed to have been last worked in the 1840s. From the mid-13th to early 19th centuries the "caves" were created and expanded from the mining of raw chalk, flint and lime-burning chalk.
