The Greenbrier Bunker — officially designated Project Greek Island — was a top-secret Continuity of Government facility constructed beneath the Greenbrier Resort in White Sulphur Springs, West Virginia between 1958 and 1961. For 34 years it served as the designated emergency relocation site for the United States Congress in the event of a nuclear attack.
The facility remained operational and classified until May 31, 1992, when investigative journalist Ted Gup published a detailed exposé in The Washington Post. The disclosure immediately triggered decommissioning. The bunker was declassified, opened to public tours in 1995, and stands today as one of the most thoroughly documented Cold War continuity of government facilities in the public record. The facility was officially transferred to The Greenbrier Resort on August 1, 1995 and is now privately owned and operated as a public tourist attraction.
This record is graded CONFIRMED. The facility has been officially acknowledged by the US government, physically verified, and is now a registered historic site with extensive public documentation including architectural plans, government contracts, and congressional records.
Constructed within limestone karst terrain beneath The Greenbrier resort. Construction was disguised as a hotel exhibition hall renovation, managed through classified USACE contracts. The 112,000 sq ft bunker is equipped with independent power, water, and communications systems capable of sustaining 1,100 persons for extended periods.
Construction begins — disguised as Greenbrier hotel renovation under Project Greek Island.
