Nuclear Bunker at the Greenbrier
This Exhibit Hall was part of the bunker -- it would house the offices of Congress.
This cooking school was to be the dining room for Congress inside the bunker.
This is what the inside of the bunker looked like -- lots of hallways with locked doors all around.
There was nothing to tell you you were entering a bunker. It was the perfect cover -- a publicly accessible area within a resort hotel.

Look to the right of the signs -- see the inset panel and the two big hinges -- that's a nuclear fallout protector door, like a huge bank vault door. These were the entrances to the shelter. This one was inside the hotel that led to the exhibit hall just beyond the door. There was also a several hundred foot long tunnel that led inside from an outdoor entrance, but that I couldn't photograph. Go to greenbrier.com and see more photos from the hotel's official website.
