The Greenbrier Bunker, formally known as Project Greek Island, is a former United States government continuity of government facility concealed beneath the Greenbrier resort in White Sulphur Springs, West Virginia. Constructed during the Cold War, its existence was a closely guarded secret for over three decades, known only to a select few resort staff and government personnel. The bunker was designed to house the entire U.S. Congress in the event of a nuclear attack, ensuring the continuity of the nation's legislative branch.
Architecturally, the facility was integrated seamlessly into the hotel's existing infrastructure, with hidden blast doors and decontamination areas. It featured extensive living quarters, a medical clinic, communication centers, and a large assembly hall that could serve as a congressional chamber. The bunker was stocked with supplies to sustain its intended occupants for an extended period, representing a major investment in Cold War civil defense infrastructure.
The project remained secret until it was exposed by The Washington Post in 1992, leading to its decommissioning. Today, the bunker is a publicly accessible museum and tourist attraction, offering tours that detail its history, construction, and the Cold War era's contingency planning. It stands as a unique and well-preserved example of a high-level government nuclear shelter, providing a tangible connection to the geopolitical tensions of the 20th century.
