15 Most Impenetrable Bank Vaults

1. Fort Knox – The United States Bullion Depository
If a bank robber was somehow able to get through the solid granite wall perimeter and past the squadrons of machinegun wielding guards and armed military, the thief would still have to contend with a 22-ton vault door.

3. The Bank of England Gold Vault
The vault walls are bombproof and so sturdy that bank staff used them for protection during WWII air raids. And when the vault doors do need to be opened, they can only be accessed by an elaborate system consisting of voice recognition, 3 foot keys and other unpublished security measures.

5. Teikoku Bank, Hiroshima – Atomic Bomb-Proof!
