We finish our series on subterranean London with a visit to the Chislehurst Caves in the outer south-east.
The ‘caves’, located in Chislehurst in Kent, are actually 22 miles of man-made tunnels which were dug out in the search for chalk – used in lime-burning and brick-making – as well as, in later years, flint for use in tinder boxes and flintlock guns.
There’s considerable debate over the age of the caves but it’s claimed the earliest mention of the complex apparently dates back to the 13th century and they are believed to have been last worked in the 1830s. The three main sections of the caves are named after the Druids, Romans and Saxons in a reference to who some believed helped to create them.
They were first opened to the public at the turn of the 20th century and have since been used for munitions storage (during World War I, to cater for overflow from the Woolwich Arsenal), mushroom growing, and, during World War II provided accommodations for some 15,000 people as one of the largest deep air-raid shelters in the country.
They also hosted music events in the 1960s when the likes of David Bowie, Jimi Hendrix, Led Zepplin and Pink Floyd were among those who performed there and have appeared in several episodes of Dr Who
These days the caves are visited only on lamplit, 45 minute guided tours, which take in about a mile of the tunnels.
