The Caspar David Friedrich Zentrum in Greifswald consists of the former home and business premises of the Friedrich family and the adjacent soap house. The family residence, where Caspar David Friedrich was born, was built in 1735 and is now a listed building. The buildings remained in the possession of the Friedrich family and their descendants for more than 200 years, spanning seven generations. The last owner transferred the property to the city of Greifswald in 1977. The Caspar David Friedrich Zentrum opened in 2004. Since 2011, the entire site has been open to visitors as a museum, exhibition and documentation centre on the life and work of Caspar David Friedrich. The centre is organised and run by the Caspar-David-Friedrich-Gesellschaft e.V., founded in 1998.
