The Greenbrier Bunker, formerly known as Project Greek Island, is a United States government continuity of government facility constructed beneath the Greenbrier resort in White Sulphur Springs, West Virginia. Designed during the Cold War to house the U.S. Congress in the event of a nuclear attack, the secret bunker was maintained with utmost secrecy for over three decades until its exposure by The Washington Post in 1992, leading to its immediate decommissioning. The facility was intended to provide a secure, self-sustaining underground command center for legislative operations.
Today, the decommissioned bunker is accessible to the public through guided tours offered by the Greenbrier resort. These tours provide a historical look at the Cold War-era infrastructure, including its large blast doors, communications rooms, and accommodations designed to support hundreds of government officials for extended periods. The site serves as a preserved example of American Cold War contingency planning.
The bunker's secrecy was its primary defense, and its exposure rendered it obsolete for its original purpose. Its existence remained one of the best-kept U.S. government secrets until the early 1990s, highlighting the extensive measures considered for national continuity during the nuclear standoff.
