Hitler's Supercity

S1 E6: A team of field investigators uncovers the clues that will recreate vanished or hidden worlds. They use the latest research, expert analysis and cutting edge graphic technology to take us back. Adolf Hitler caused more death and destruction than any other individual in history. But he also had plans to build on a massive scale: to construct a new Germany, based on his Nazi ideology, and place his people's achievements on a par with the great civilizations of ancient Greece and Rome. Our investigators piece together a picture of how Hitler wanted Germany to look from the ruins of what was built, and from the never-implemented plans of his architect, Albert Speer. In the Nazi heartland of Nuremberg, we recreate the spectacle of the Zeppelin Tribune: where 60,000 people could overlook a parade ground begin enough to accommodate one million. We reveal the real purpose of the giant stadia Speer planned to hold the Olympic games -- including, with seating for 405,000 people, the largest sports venue in the world. And we rebuild, with computer-generated images based on Speers own plans, the enormous monuments that Hitler planned for himself: the Triumphal Arch -- twice the height, and four times the width of Paris' Arc de Triomphe, and the People's Hall -- a domed structure, so big that the Eiffel tower could fit inside it. Monstrous, intimidating, built on slave labor: this is a Lost World, that if World War II had gone differently, we would now inhabit.
