The LehmbruckMuseum is distinguished by a collection of international 20th century sculpture unique in Europe and an admirable combination of sculpture park and striking modern museum architecture. The museum is the product of the Museum Association, founded in 1929, and the City Museum of Art, set up in 1929.

The museum building was completed in two stages (1964-1987). The inner area, 5,000 square metres in extent, houses a total of some 500 works - starting with the life's work of Wilhelm Lehmbruck and the German painting of his time - by more than 200 artists from some 20 countries, and includes over 300 pieces of sculpture. The sequence of the rooms is monographic and thematically arranged, with open ordering. The rooms include paintings, work on paper and in new media.
