Project Greek Island, the secret bunker that was never used
In the late 1950s, the United States government approached The Greenbrier Hotel and sought its assistance in creating a secret emergency relocation center to house Congress in the aftermath of a nuclear holocaust. The classified, underground facility was built at the same time as the West Virginia Wing, an above-ground addition to the hotel, from 1959 to 1962.
For 30 years, The Greenbrier owners maintained an agreement with the federal government that, in the event of an international crisis, the entire resort property would be conveyed to government use, specifically as the emergency location for the legislative branch.
The facility was decommissioned in 1992 after the program was exposed in a U.S. newspaper article.
