We have many different themes about a lot of subjects. Here are some examples.
Since the foundation of the Deutsches Reich by Otto von Bismarck on January 18, 1871, Berlin is the capital of what we now call Germany. During the National Socialist regime under Adolf Hitler the center of power was located particularly in the vicinity of the Wilhelmstrasse. All that remains of the here located Old Reich Chancellery (1878), the New Reich Chancellery (1938), the Vorbunker and the Führerbunker after the Russian demolition works of the last century are underground remnants. Yet there is still plenty to see in Berlin for the visitor interested in World War Two.
