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.
