Neue Nationalgalerie, by Mies Van der Rohe , located in the Museum District of Berlin and off the Spree River. It is home of 20th century European painting and sculpture ranging from classic modern art to art of the 1960s. The collection includes works by Munch, Kirchner, Picasso, Klee, Feininger, Dix and Kokoschka, or so I have read. I had the unfortunate luck of being there when the exhibition was preparing for a Picasso exhibit. I was looking forward to Kirchner's "Potsdamer Platz", which was painted shortly after the first WW, and now stands in contrast to the recent changes that are taking place on the site a few metres away from the gallery.
