Museum Gemäldegalerie am Kulturforum in Berlin

You're standing at the Gemäldegalerie in Berlin, at the Kulturforum, just west of Potsdamer Platz. From the outside, the building may not look like much. It's modern and understated, designed by Munich architects Heinz Hilmer and Christoph Sattler, and finished in 1998. But inside hangs one of the world's leading collections of European painting, from the thirteenth to the eighteenth century.
