Hidden, Forbidden & Off-Limits by Steve Higgins

There are as many as 60 miles of underground tunnels beneath Wiltshire, England alone. While some of these abandoned and decaying subterranean spaces are playgrounds for urban explorers, others have been shrouded in secrecy for decades. This bunker-busting journey to some of Britain's dark and forgotten places will give you the chance to peek behind the heavy blast-proof doors of some of the country's best-kept underground secrets.

Embrace the darkness and uncover the forgotten history that is waiting to be discovered below ground — the weird mix of fact, folklore, and mythology. Venture into decommissioned command bunkers, probe now-mothballed Cold War nuclear hideouts, uncover the World War II secrets that are still hidden beneath the British countryside, and find out how the tunnels left behind by 19th-century quarrymen provided a safe haven for these covert schemes.

A word from the author

There are plenty of stories to be told on this underground adventure, from the tales of covert government agents skulking around the secretive underground base in Corsham formerly known as RAF Rudloe Manor, to the wartime spirits of a cloak-and-dagger underground aircraft factory in Kidderminster. There's even wild rumours linking one of the UK's most secure underground locations to a government department tasked with gathering intelligence on extraterrestrial encounters.

Circumvent the anti-trespass barriers, dodge the bats, and descend into these hidden landscapes to discover why people are so fascinated by the unknown worlds beneath their feet.
