This time, I will suggest a different trip across Berlin.
There are four time options: 1869 - 1893 - 1926 - 1957.
Up to you to make the choice. The final discovery: the history of the places and streets.
I am terribly sorry, but was not prepared to take some pictures. Maybe a next time.
Anyway, a(nother) smart idea to promote the city and raise the interest in its history.
