One of the iconic places of Friedrichstrasse, where the border of the division of Berlin into the western and eastern sectors passed, there are many tourists, souvenirs, cafes.
When I am in Berlin, I definitely visit this interesting historical place. There are always a lot of tourists, I always take photos for memory and communicate
An interesting place is the preserved border crossing in Berlin.
The museum nearby is rather one-sided, the division into black and white from the point of view of the winners in the cold war is sometimes touching ;-)
