WEST BERLIN
The center of former West Berlin was... hmm... I don't know, probably along the main, representative shopping boulevard Kürfurstendamm (Ku-damm).
EAST BERLIN
The center of former East Berlin was at Alexander Platz.
NEW BERLIN
The center of reunificated Berlin is at the place or rather two places where the Wall stood: around Potsdamer Platz and around Branderburg Gate.
Confused? Just check the map and learn/remember the names of a few of central districts ("bezirk") of Berlin:
- Mitte,
- Tiergarten,
- Charlottenburg,
- Kreuzberg.
Most of tourist attractions are located in the above 4 district (zone A + B for transportation tickets).
