39. Nordhausen (2002)

It was the world’s largest underground factory–seven miles of tunnels built to manufacture Hitler’s secret weapons, primarily the V-2 rocket. But Nordhausen kept more than one secret. Technology and torture went hand-in-hand–25,000 concentration camp workers died there–and some of those associated with Nordhausen later helped take America to the moon.
