7. Recipe for Coca-Cola
It’s said that the recipe for Coca-Cola is protected in a Georgia vault. While the vault may be viewed, the recipe, alas, cannot. This closely guarded trade secret is scrupulously maintained by just a few of the company’s employees. If you want to at least get close to the formula, you’ll need to travel to Atlanta’s World of Coca-Cola vault exhibit. That’s the closest you’ll get to the top secret formula of the world famous beverage brand.


8. Bank of England Vaults
The formula for Coca-Cola is one thing, but piles and piles of gold are another. Unfortunately, you won’t be allowed to witness the lustrous gold stashes in the vault of the Bank of England. You’d have to make like Harry Potter to finagle your way into this lock-and-key setting that only a few bank employees (whose names are kept secret) can enter.


9. Area 51
Area 51, also known as Groom Lake, is a top secret military base and airfield located in southern Nevada. It has been a site for experimental aircraft and weapons testing, but no civilian is permitted to really know what goes on there. The CAI refuses to disclose any details about it, which has lead to many a conspiracy theory about Area 51. Of course, the most famous one is that they’re hiding crashed alien spaceships or working on energy weapons. Whatever is going on there, you’ll probably never get close enough to find out. The entrance to the zone says they can use deadly force if unauthorized people try to trespass.
