The Museum of World Cultures (German: Museum der Weltkulturen) is an ethnological museum in Frankfurt, Germany. Until 2001 it was called the Museum of Ethnology (Museum für Völkerkunde).
It was founded in 1904, as a civic institution, to bring together the ethnographic collections of the city of Frankfurt. In 1908 the museum moved into the Palais Thurn und Taxis in the city centre. In 1925 the city acquired the collections of the Institute of Cultural Morphology (today the Frobenius Institute), founded by the ethnologist Leo Frobenius. He relocated to Frankfurt along with the institute and become an honorary professor of the University of Frankfurt. In 1934 he became the director of the museum. The roles of museum director and institute director continued to be occupied by the same person (including Frobenius's successors) until 1966, when the university became state-run, since when the museum has again been run by the city.
Significant parts of the collection were lost when the Palais was destroyed by bombs in World War II. However, some items had already been evacuated from the Palais – these survived the war, and in 1973 they were put on display in an old villa on the banks of the Main, where they have been ever since. The Museum of World Cultures therefore counts as one of the earliest museums on what is now the Museumsufer.
The museum has expanded since 1973 and now occupies three adjacent buildings on the Schaumainkai – nos. 29 (the main building), 35 (the original villa), and 37 ("Gallery 37"), which were acquired and/or rebuilt in the 1980s. The collections include over 65,000 objects from Oceania, Australia, Southeast Asia, the Americas, Africa and Europe. Gallery 37 hosts exhibitions of contemporary works by Indian, African, Oceanian and Indonesian artists.
