Cities of the Underworld
Season 2. Disc 3DVD - 2008
First, Below Moscow's crowded streets lie the reminders of its war-torn past and pieces of Stalin's terrifying legacy from the tunnels used to hide from Stalin's henchmen, to secret metro systems and hidden bunkers. Then, the Holy Land is full of holes that hide secret chambers and hidden vaults that riddle the landscape and conceal countless mysteries. Last, Don delves into D.C.'s subterranean defenses and takes you everywhere from top-secret, high-tech super bunkers to the underbelly of the National Mall.
