The Germans have a remarkable intelligence, and the design of the bomb shelter is very practical. Both disaster and flight will work.
A somewhat historic air defense cave is a reflection of the wisdom of the Germans, unique design, high security. Worth learning.
Nuremberg is also a very important military city in Germany during World War II. There are many historical buildings left over from the war. The air-raid shelters will be in the old town, with very good tunnels and buildings, which can be visited inside.
The heritage left during World War II, air-raid shelters were not only used for Tibetans, but also used to protect precious cultural works of art.
Here I feel that there is a sense of picture with historical precipitation.
