Chislehurst Caves are a series of intersecting man-made tunnels and caverns covering some 22 miles (35 km) in Chislehurst in south east London, England. From the mid-13th to early-19th centuries the ‘caves’ were created from the mining of flint and lime-burning chalk.
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 1830s.
When the aerial bombardment of London began in September 1940, the caves were used as an air raid shelter. Soon they became an underground city rising to some 15,000 inhabitants (who each paid a penny to enter). The tunnels were fitted with electric lighting, toilets, washing facilities, a chapel was built and also a hospital.
The caves were located close to Chislehurst railway station and many people arrived there to then enter the shelter. Shortly after VE Day the shelter was officially closed. There has been only one child born in the caves, christened in the cave chapel with the unfortunate name of Cavena Wakeman, who endured the name until she turned 18, when she legally changed her first name to Rose and using Cavena as her middle name.
