The simple glass cube of the Kunstmuseum contrasts with the lavish historic architecture of its surroundings, while not being intrusive thanks to its transparency. Its collection of modern art pieces is now over 15,000 strong, but obviously not all of them are displayed at the same time, but rather selected ones in temporary thematic exhibitions. Apart from exhibition spaces, the building hosts a large thematic bookstore, as well as a high-end restaurant Cube and o.T. bar, affording splendid views over the Schlossplatz.
