Abteiberg Museum in Mönchengladbach is known in Germany for its comprehensive collection of contemporary art and the avant-garde collection. Johannes Kladders was the initiator of the museum, who later became its first director. The museum design was ordered to the Austrian architect Hans Hollein. The resulting building is considered a model of post-modernism.
Hollein himself described the concept of the building in Mönchengladbach as "museum, as an adventure". According to his idea, something new must wait the visitor around every corner. Hence the idea of multidimensionality: the museum has elevated and underground parts. 1971 is considered to be the year when the museum was founded, though it was moved to the current post-modern building in 1982. Abteiberg Museum is famous for the variety of avant-garde. Its collection reflects all the art movements of the second half of the twentieth century: modern, post-modernism, constructivism, pop art, expressionism.
