A local attraction is Chislehurst Caves. The caves are considered to be of very ancient origin. Originally they were used to extract flint and chalk. During World War II, thousands of people used them every night as a bomb shelter. There is even a chapel. A girl was born in the caves during World War II, and her name was "Cavina". The caves have also been used as a stage for live music; Jimi Hendrix, The Who and The Rolling Stones have played there. The caves are said to be haunted, and Druids are said to have made grisly human sacrifices in their depths. Several TV programmes and movies have been filmed there, including episodes of "Doctor Who". Tours are available most days, and on Sundays there is an particularly long tour, lasting about an hour and a half.
