City AM partnered with Joolz from Joolz Guides to take an exclusive first look inside London’s deepest underground tunnels — a hidden network 40m beneath Chancery Lane that’s being transformed into the city’s newest and most unique tourist attraction.
These tunnels, built initially as WWII bomb shelters, later became a top-secret MI6 intelligence hub during the Cold War and are thought to have inspired James Bond creator Ian Fleming’s Q branch!
Now, after decades of secrecy, they’re set to reopen to the public in a £120 million redevelopment project.
