The Jewish Museum exhibits the social, political and cultural history of the Jews in Germany from the 4th century to the present. The design of the Museum engenders a fundamental rethinking of architecture in relation to its program. The new extension was completed in January 1999, 10% under budget, and opened fully installed to the public in September 2001. SDL worked with Lubic & Woehrlin Gmbh to complete this project. In five years, more than 4,000,000 people have visited the museum.
