From te Potsdamer Platz we walked to Checkpoint Charlie.
Here you see a replica of the cabin as the original cabin has been placed in a museum.
By then our feet were killing us so we took the U-bahn to the KaDeWe a big warehouse near the Gedächtniskirche. The church is located on the Kurfürstendamm, one of the most famous avenues in Berlin.
Before taking the train back to our hotel we walked along the Kurfürstendamm. We didn't buy a thing as prices here are much too high for us.
