Dome inside Berlin Schloßstraße Museum Berggruen. The Berggruen Museum (also known as the Berggruen Collection) is a collection of modern art classics in Berlin, which the collector and dealer Heinz Berggruen, in a "gesture of reconciliation", gave to his native city for a price well below its actual value. The most notable artists on display include Pablo Picasso, Alberto Giacometti, Georges Braque, Paul Klee and Henri Matisse. The Berggruen Collection is part of the National Gallery of Berlin. The collection arrived in Berlin in 1996, with Berggruen's return to his native city after six decades in exile. In 1988 he had given about 90 Klees to the Metropolitan Museum of Art, and in 1990, he had agreed to make a five-year loan (renewable by mutual agreement) to the National Gallery in London of 72 paintings and drawings by Paul Cézanne, Georges Seurat, Vincent van Gogh, Pablo Picasso, Georges Braque, and Joan Miró. Also in 1990, negotiations with Museo Nacional Centro de Arte Reina Sofía for the Berggruen collection to be shown in Madrid fell through. Berggruen initially lent the collection, which he had assembled over 30 years, to the Prussian Cultural Heritage Foundation (PCHF). He finally sold it to the PCHF in December 2000, for the "symbolic" price of 253 million marks, well below its then estimated value of 1.5 billion marks. Today it is exhibited under the title "Berggruen Collection – Picasso and His Time" as part of the National Gallery of Berlin, in the West Stüler Building on Schloßstraße, opposite Charlottenburg Palace.
