It’s roots firmly in the 19th century, this sleepy town just south of Berlin was not only home and HQ to German high command through both world wars, but also played a crucial role in grooming the Reich’s elite, the olympic sports teams, and housing up to 75,000 secretive Soviets during Russia’s occupation of Germany. Today only ruins remain, and with bunkers below as numerous as buildings above ground you’d be hard pushed to find a site more richly steeped in history.
