Fort Knox, United States
If you fancy getting your hands on America’s hoards of gold then you will have your work cut out. This Kentucky military base has been used for many purposes over the years but is currently used to house the US’s gold.
As you can imagine security here is pretty tight. You know the saying ‘harder to get into than Fort Knox’? Well it’s true. Hurdles you’d have to overcome to get your hands on piles of the shiny stuff include barbed wire, minefields, electric fences, armed guards and security cameras. If you manage to get that far bear in mind there are Apache helicopters poised and waiting for the signal to fire. Good luck!
