 The collection includes paintings, sculptures, objects and photographs from the 20th century, plus over 2,500 graphics, spanning Expressionism through classic modern art to the present day.The museum's original location, from 1947 until 2009, was a building on the Ostwall (a road in central Dortmund following the old city walls), including a small sculpture garden.The previous building on the site had been the "Museum für Kunst und Kulturgeschichte" (MKK), a municipal art collection, from 1911 until its destruction in World War II; before 1911 it housed the old Westphalia Mining Authority.
