On the occasion of the 100th anniversary of the switchgear plant in Siemensstadt, the Siemens Historical Institute is now presenting the “Siemens in Berlin” app. Explore the history of one of Berlin’s oldest production facilities – from its beginnings to the present day. But the app offers much more: it brings to life a total of ten historical Siemens locations that are still in existence today – from Werner von Siemens’ villa in Charlottenburg to the test route of the world’s first trolleybus in Halensee, on what is now the Kurfürstendamm. Take off from the television tower on Alexanderplatz for a flight tour of important Siemens locations in Berlin.
