The official plans for Site R called for an underground command control center that consisted of miles of tunnels and access shafts to the surface, but no will say what’s actually on site. It’s rumored that Raven Rock is home to an entire underground city — complete with streets and pumped-in air — that can survive a nuclear blast or an electromagnetic pulse. Some people say the bunker can sleep 3,000 people, houses a large supply of MREs (meals ready-to-eat) and features a special presidential apartment.

 

Although the facility was constructed around the same time as The Greenbrier bunker and Mount Weather, far less is known about this government complex. Documents referencing Site R simply say “it is unlawful to make any photograph, sketch, picture, drawing, map or geographical representation” of the site. Of course, in the age of Google Earth, this degree of secrecy seems somewhat futile.
