Situated on a 6,500 acre estate in the Allegheny Mountains of West Virginia, the Greenbrier is classic American resort that features a 40,000-square-foot spa. But until The Washington Post broke the story in 1992, most guests arriving for a retreat had no idea that the hotel boasted yet another amenity: the top-secret Emergency Relocation Center. In 1958, the hotel agreed to build for the government a 112,544-square-foot fallout shelter, specially designed for members of Congress and their support staff. It also agreed that in the event of an international crisis, the entire resort would be handed over to the government for use—much as it was during WWII, when it became a hospital. Today, the decommissioned bunker is open for 90-minute tours, where one can revel in Cold War artifacts and view the advanced communication room, which featured a probe designed to monitor after a nuclear attack, a television production area and audio recording booths, and a the clinic area.
