In the early 19th century, then-crown prince, Friedrich Wilhelm IV, conceived the idea of turning an island in the River Spree into a "sanctuary of Art and Science." This began a period during which major museums were built while newly-rich Germany began buying up enormous quantities of art. The intent was to make Germany's museums as impressive as any in Britain or France; and it succeeded. Berlin, by the turn of the 20th century was one of the richest repositories of art on the planet.
With the coming of Hitler, however, what had been superb collections of contemporary German and European art were decimated: works were either sold off or simply destroyed. Impressionism, Expressionism, Cubism, all the newer movements in the art world of the times were declared "depraved." The Nazis spoke of "entartete Kunst" and it was to be eliminated.
After the war, what works were left in the vaults and storage rooms of Berlin's museums were shared out between the two Berlins. Much of the Egyptian collection, for example, wound up in the Ägyptisches Museum (Egyptian Museum) in Berlin-Charlottenburg, while other collections, such as the wonderful Pergamum collection remained in East Berlin's Pergamum Museum in Berlin-Mitte.
Now that the city has been reunited, the collections are being rearranged; the Museum Insel will be restored to its pre-eminent position as a storehouse for European and world cultural and artistic history.
