Greenbrier Bunker

The Greenbrier Bunker, officially known as Project Greek Island, was a secret United States government continuity facility located beneath the Greenbrier hotel in White Sulphur Springs, West Virginia. Built in 1958-1961 during the Cold War era, this underground bunker was designed to house and protect the United States Congress in the event of a nuclear attack. The facility remained operational until 1992 when its existence was revealed by The Washington Post, after which it was decommissioned and later opened for public tours.
