The Greenbrier Bunker was one of America’s best-kept secrets for decades. Beneath the Greenbrier Resort in West Virginia, a bomb shelter was hidden from the general public. It was created for members of Congress in the event of an emergency, stocked with months’ worth of food and supplies. The bunker was kept a secret for over thirty years, and it was built alongside the Greenbrier Resort, in the town of White Sulphur Springs.

Even the official historian of Greenbrier, Bob Conte, knew nothing about the bunker. Conte had all sorts of records and photos from the property, but nothing that revealed information about the bunker. It turns out that the bunker was built in case of an emergency during the Cold War. The space of the bunker has been compared to that of a Walmart store, with thick, concrete walls and an extensive air filtration system. Rows of metal bunkbeds line the walls, with enough beds for 1,100 people.

The building of the bunker was called “Project Greek Island,” and hotel workers and locals were told the construction was for a new conference and exhibition center. It was even used for conferences by thousands of people who had no idea that it was actually designed to be a secret bunker. Down the hall from the sleeping quarters, there was a room designed to be the floor for the House of Representatives. A group of secret government employees disguised themselves as technicians, but they were really some of the only people in the world who knew about the bunker. It was their job to make sure there was a constant six-month supply of food, the most up-to-date pharmaceuticals, and everything that the members of Congress would need in the event of an emergency.

The bunker was exposed to the public in 1992. Today, the Greenbrier property is home to not only the Greenbrier Resort, but also the Presidents’ Cottage Museum. As over twenty-five presidents have stayed there, the museum shows their experiences, the property’s history, and, now, part of the bunker. There is a new emergency shelter in place, but only a handful of people know its whereabouts.
