First, a tool in the fight against Nazis during World War II, this sea platform was occupied by Major Paddy Roy Bates in 1967, and established as a sovereign micro-nation off the shore of the United Kingdom. It has it's own flag, passport, and currency, however they are not widely used. It has it's own laws, and it's own constitution, and while not technically a sovereign nation, the British courts have ruled it is out of their jurisdiction as it is three miles off shore, and they have received a German diplomat.
This is quite a powerful Fort Awesome.
