On Tuesday, I visited Charlottenburg Palace. I didn't take any photos inside but with hindsight, I should have purchased a photo pass. Some rooms were quite impressive.
Two photos I took on my way to Schloss Charlottenburg:

I forgot to tell you that I spotted another Germany celebrity, Stefan Mross, a famous Volksmusik artist. He was on Friedrichstrasse, not far from my hotel. Don't worry if you have never heard of him... I only know him through German gossip magazines for housewives that I've been reading since I was a kid.
