If Britain had been attacked by a nuclear bomb during the Cold War, its government would have survived by retreating to a massive, 35-acre complex buried beneath the county of Wiltshire. I call it a bunker in the headline, but it was more like a small town—large rooms linked by roads, built on the site of an abandoned quarry. Known as Burlington, it could house 4000 people and feed them all for 3 months. It was also home a broadcasting studio and hospital.
The whole thing was kept secret up until its decommissioning in 2004. You can take a tour in the BBC news clip above, or check out the photo galleries and interactive maps on the BBC's Burlington site. With few upgrades since the 1960s, the place looks like a time capsule. An awesome, gigantic time capsule. It's easy to understand why the news presenter in the video is rubbing his hands together gleefully as he's about to get on the elevator to go down. I'd be excited, too!
