From the earliest bunkers of WWI through the ultra-futuristic ones of tomorrow's wars, we trace the story of defensive fortifications. In the constant struggle to hold off ever more potent forms of attack, bunkers function in a variety of forms. Three mammoth block structures comprise a submarine bunker at Lorient, France, able to house 20 subs . We visit Churchill's Cabinet War Room and Hitler's Berlin bunker, as well as backyard Cold War bunkers and those that protect nuclear weapons themselves.
