The Voelkerkundemuseum (Ethnological Museum) had its first exhibition in 1924. In addition to a wide collection of artworks and ethnological objects from Asia, Africa, and Oceania, the museum hosts changing art and culture exhibitions.
The Portheim Foundation of Science and the Fine Arts was etablished by Victor Goldschmidt in 1919. In 1922, he bought the "Palais Weimar" to present and display the precious collection in a suitable setting. The collection included minerals, material of early history, European ethnology, icons, and early printings and ethnographics. During the Second World War, the valuable library and the collection of minerals were sold, the folklore stocks were plundered at the end of the war. The ethnological collections, however, survived and were enlarged continuously. They are open to the public.
