The Nationalgalerie collection contains around 4,000 works of 20th century art. This partial collection is comprised mainly of the Nationalgalerie’s own collection. It also encompasses the Marx Collection, the Ulla and Heiner Pietzsch Collection and parts of the Marzona Collection, whose home is the Staatliche Museen zu Berlin (National Museums in Berlin). The Kunstbibliothek (Art Library) and the Kupferstichkabinett (Museum of Prints and Drawings) of the Staatliche Museen zu Berlin will get additional exhibition areas in the new museum building.
The Nationalgalerie’s collections of 20th century art document all of Europe’s and North America’s major art movements. But its exhibition options are limited: until now, the extensive collection has been presented in the Neue Nationalgalerie. For this reason, the art of the 20th century could only be presented in part and in rotating exhibitions in the past decades.
