Secret Nuclear Bunker at The Greenbrier

The Greenbrier, a luxury resort in West Virginia, has a secret nuclear bunker built to house the entire US Congress in case of a nuclear holocaust. The bunker, known as 'Project Greek Island', was constructed from 1959 to 1962 and remained hidden for 35 years until it was revealed in 1992. It was never used as an emergency location and was decommissioned after its existence was made public.
