I didn´t know that it was sooo cold in Berlin...
I didn´t have enough egergy to enjoy sightseeing because of bad weather and tiredness.
I went to see Gedenkstätte und Museum Sachsenhausen(this is like "auschwitz concentration camp") ,Kaiser-Wilhelm-Gedächtnis-Kirche and Brandenburger Tor.
Sightseeing related to wars makes you feel tired, which cannnot be helped...
According to my first impression, Berlin is like a modern city. So most of buildings are modern except for historical building.
I will take a train for Munichen a quarter later. I´m looking forward to meet one of my friends there :D
I hope I can sleep well in a sleep-train.
