I spent part of my Saturday solo-exploring Berlin's Neue Nationalgalerie ("New National Gallery"), designed by Mies van der Rhoe and completed in 1968, a year before the celebrated architect's death. Beneath the entry level — which is empty save for a contemporary installation on the ceiling — are the actual galleries, which house many important 20th-century works of European painting and sculpture. My Flickr set has all my photos, along with captions identifying what's what.
