The Greenbrier Nuclear Bunker, also known as Site RT, was a top-secret United States government facility constructed beneath the historic Greenbrier resort in White Sulphur Springs, West Virginia. Designed during the Cold War, its existence was classified for nearly three decades, known only to a select few resort employees and government personnel. The bunker was engineered to serve as a secure relocation site for the United States Congress in the event of a nuclear attack, ensuring the continuity of government operations.
Architecturally, the bunker was a massive underground complex with thick concrete walls and ceilings, capable of withstanding a nearby nuclear detonation. It included extensive living quarters, a hospital, communication centers, and chambers for the House and Senate to convene. The facility was seamlessly integrated into the resort's existing infrastructure, with hidden entrances and blast doors concealed within the hotel's foundations and parking areas, making it indistinguishable from the surface.
The bunker's secrecy was maintained through a cover story that the complex was merely a resort storage facility. It remained operational from the early 1960s until its dramatic declassification in 1992, when a Washington Post article exposed its true purpose. Today, the facility is open to the public as the Greenbrier Bunker Museum, offering tours that provide a stark glimpse into Cold War-era civil defense planning and the lengths taken to protect national leadership.
