If you ever believed that secret, tough-to-break-into or inaccessible locations existed in movies like Kingsman alone, or that no one could match Jason Bourne in marksmanship out of the virtual screen, you couldn't be more wrong. When it comes to government data, religious texts, historical evidences, billions of dollars in gold and diamond, or even seeds, people have created powerful security systems, so intricately designed that it will put superheroes to shame. Here's a list of some of the world's most difficult places to break into, even in your dreams. Fort Knox - Kentucky, U.S.A It is guarded by a team of heavily armed guards, electrified fences, a 22-tonne vault door and a password no one knows fully. What it guards: Home to the US Bullion Depository, Fort Knox not only stores thousands of tonnes of gold, but is also said to house important historical documents, such as the Magna Carta. If you plan on breaking into Fort Knox, like James Bond in Goldfinger, you have to get past four fences, two of which are electrified and then sneak past a team of armed guards. After avoiding all the video cameras on your way, you will need to blast through the four feet thick granite walls held together by 750 tonnes of steel. After all this, you will need to work your way through the maze of locked doors till you find a 22-tonne vault door. For the combination to the vault, all you need to do is find all the members of Fort Knox staff because every knows a small part of the combination - nobody knows the whole thing. If you are live through all of it, you are the world's new superhero.

Svalbard Global Seed Vault - Spitsbergen, Norway

It can survive earthquakes and a nuclear holocaust and is one of the toughest to break into.

What it guards: Designed to store a wide assortment of seeds in an effort to preserve crop diversity, it is home to over 500,000 plant species from around the world. In case doomsday casts its spell upon us, we will be able to revive these plant species.

620 miles away from the North Pole, and distanced by hundreds of miles of ocean, it’s so deep that it is resistant to a nuclear holocaust, and can avoid severe earthquakes. It is located 430 feet above sea level so that it is secure from any possible sea-level rise. The vaults resting behind four heavy steel doors, make for one of the toughest vaults to break into in the world.

The Iranian Gold Reserves - Location Unknown

No one knows where it is - which makes it completely impossible for anyone to break into.

What it guards: Iran has enough gold to prevent a freeze.

What makes the vault holding Iran’s gold reserves impenetrable is that nobody can say for sure where it is. What better security than not knowing the location of the reserves unless you stumble upon it with a (gargantuan) bit of luck.
