The North Rhine-Westphalia Art Collection (Kunstsammlung Nordrhein-Westfalen) is spread across three locations in Düsseldorf. 

The largest collection, K20, is located in Grabbeplatz, an ultra-modern building with a façade of polished black granite, which is itself a work of art. 

This vast gallery houses numerous works of modern art, including a notable collection of paintings by Paul Klee. 

K21, in the 19th-century Ständehaus building, includes a variety of installations focusing on modern painting and drawing, as well as sculpture and film, with works by Thomas Schütte, Reinhard Mucha, and Thomas Hirschhorn.
