Chislehurst Caves

The woodlands of Chislehurst hold a secret beneath their roots. Thirty metres below ground is a complex of man-made caves carved out of the chalk by Druids, Saxons and Romans. Since then the caves have been turned to all sorts of purposes, including an ammunition dump in World War I and a mushroom farm; during World War II, they acted as Britain’s largest bomb shelter. Most of the underground scenes in the TV series 'Merlin' were filmed here. The 45-minute lamplit tour covers a mile of the tunnels; children will enjoy locating the Druid Altar, the Caves Church and the Haunted Pool.
