Berlin is a big German city. It is a must see as it is full of history and everybody heard of it. We wanted to learn more about World War II and this stop helped, along with the next stop and the visit of Dover Underground tunnels in United Kingdom a few weeks ago. We walked a lot in Berlin, just like anywhere else so far, even if Berlin has a well developed public transit system. We saw the Brandenburg Gate, the Reichstag, the Holocaust Memorial, the East Side Gallery and of course the Wall. The East Side Gallery is a big part of the wall which is covered with paintings from different artists. We were only one day in Berlin visiting all the sights but we could have easily spent more time there.
