10 Mysterious Places You Aren’t Allowed To Visit

7. Coca-Cola Vault, United States

We move from warfare to soft drinks, and onto something a little more tasty (sorry).

Coca-Cola needs no introduction. It's one of the world's favourite drinks, is responsible for excited faces when that Christmas ad comes on telly each year and has been a long-standing tradition since launching 131 years ago. Somehow, The Coca-Cola Company have been able to keep the drink's recipe secret all that time.

A secret vault in Atlanta houses Coke's formula, and it's possible to visit the place to get a sneak peak. Just kidding, but sugar-hungry tourists can buy tickets to explore the drink's history and (according to the worldofcoca-cola.com website) "get closer than ever before" to the ingredients.

The vault is sealed shut however, meaning a quick tour and glimpse of where the recipe is kept is all visitors get before being ushered out into the gift shop.
