Architect Renzo Piano constructed the Zentrum Paul Klee in June 2005. Located in Bern, the museum exhibits about 150 (of 4000 Klee works overall) in a six-month rotation, as it is impossible to show all of his works at once. Furthermore, his pictures require rest periods; they contain relatively photosensitive colors, inks and papers, which may bleach, change, turn brown and become brittle if exposed to light for too long.[3] The San Francisco Museum of Modern Art has a comprehensive Klee collection, donated by Carl Djerassi. Other exhibitions include the Sammlung Rosengart in Luzern, the Albertina in Wien and the Berggruen Museum in Berlin. Schools in Gersthofen, Lübeck; Klein-Winternheim, Overath; his place of birth Münchenbuchsee and Düsseldorf bear his name.[citation needed]
