3. There’s a Cold War Bunker Inside the Brooklyn Bridge

The Brooklyn Bridge is one of the city’s most recognizable landmarks but most people who walk or drive by are unaware that there’s a cold war bunker inside one of the masonry foundations on the Manhattan side. Discovered in 2006, the time capsule was discovered by city workers and had lain untouched there for fifty years. As reported by The New York Times, the vault was filled with “water drums, medical supplies, paper blankets, drugs and calorie-packed crackers — an estimated 352,000 of them, sealed in dozens of watertight metal canisters and, it seems, still edible.”
