The Bank of England Vaults
The Bank of England Vaults contain lots of bullion. The second oldest central bank in the world is off limits to the public, as it contains hundreds of thousands of gold bars. The floor space over this vault covers a region about the size of the third-tallest building in London (Tower 42). The keys to open the vault door are 3 FEET LONG! The gold deposits in the vault are estimated to hold a value of 156 billion pounds.
