This bunker was built in Germany in 60 years of 20 th century.


He was to be a refuge for the ruling elite in the case of a nuclear war.


Was he near Bonn, and the tunnel system consisted of a total length of 17 km.


Its construction took 12 years and 5 billion marks.


Fortunately, he never needed.


At the end of his 90 x closed and dismantled. At this time of a bunker left alone concrete tunnels.


There is also a museum, which workers several rooms.


These pictures made at a time when there was still a bunker. I signed them to be clearer.
