A really nice building with many interesting exhibitions and one permanent collection including various famous artists such as Magritte, Picasso, Lichtenstein...
Berlin is in my opinion the cultural heart of Europe at the moment. There is just so much going on, gallery openings, exhibitions, music festivals, amazing nightlife...you just do not know what to do first when you arrive there.
It is the art event of the year in Berlin and I had the chance to admire this art happening myself where sometimes the people are more interesting than the art!
