If you have a thing about trains and transport generally then you might find your inner geek with Berlin Hauptbahnhof. Its like a five level glass cathedral to train travel. I say five levels as ‘five floors” wouldn’t really give the right perspective of how big it is. This is the top level where the S-bahn and long distance trains arrive and leave from. The lowest level is 15m underground and has services such as the U-bahn. In between are a variety of transport options plus the sort of boutique, food and general shops and restaurants you would find in any large modern shopping centre.
Anne Frank portrait by the English artist Jimmy C. on the wall outside the exhibition ( or Anne Frank Zentrum – http://bit.ly/1ljx7ZP ).
The exhibition is worth taking your time over, the matter of fact presentation of the horrors mesh with the personalised accounts from Anne Frank, her family and friends.
By the way, don’t be put off by the laneway at Rosenthaler Strasse 39. There is lots of graffiti but also a couple of other small museums including that for Otto Weidt (http://bit.ly/RDzUTu )
