Deep in the mountains of Bavaria is a concrete doorway set into the side of the mountain. Even in the height of summer, the thick steel door is cool to the touch, and drips with condensation. From the edges of the door frame comes a chilling cold breeze. It isn’t marked on any tourists guide maps, as the government would prefer that you had no idea that it exists.
Behind the steel door lies the underground secret bunker complex of Adolf Hitler.
I went exploring the four miles of tunnels, secret apartments and bunkers that were to form the last fighting place of the Nazi party inner circle after the fall of Berlin.
