The Greenbrier Bunker, officially known as Project Greek Island, was a secret United States government continuity program located beneath the Greenbrier resort in White Sulphur Springs, West Virginia. Built during the Cold War era, this underground facility was designed to house and protect members of Congress in the event of a nuclear attack. The bunker remained operational from the 1960s until 1992, when its existence was revealed by The Washington Post, leading to its decommissioning.
Today, the facility has been converted into a tourist attraction, offering visitors a glimpse into Cold War-era military preparedness and the secretive world of government continuity planning.
