2009, the Kunstsammlung inaugurated the former home of the Galerie Schmela, located at Mutter-Ey-Straße 3 in Düsseldorf-Altstadt, as a venue for exhibitions, discussions and other activities. After remaining closed for more than two years during comprehensive renovations and the erection of an extension building, the K20 at Grabbeplatz resumed operations as an exhibition venue in July 2010. Available now for the collection and for temporary exhibitions is a generous surface area. The first artists to exhibit there were Belgian illustrator Kris Martin and German sculptor Michael Sailstorfer, who created accessible installations for the two galleries of the new building, namely the Klee Halle and the Konrad und Gabriele Henkel Galerie, which together offer almost 2.000 m². During the first two weeks after the reopening alone, nearly 60,000 visitors took advantage of free admission to the Kunstsammlung. The museum welcomed its 100,000th visitor on 21 October 2010. Contributing to the new and more emphatic public presence of the Kunstsammlung – which is now able to display the art collections of this federal state more comprehensively than ever before – is the large-scale mosaic mural "Hornet", composed of colorful tiles and the work of American artist Sarah Morris. With its length of 27 meters, it has become attractive landmark on the newly created Paul Klee Platz along the rear façade of the K20. Featured on a regular basis in the venues of the Kunstsammlung Nordrhein-Westfalen alongside presentations of the permanent collection are internationally acclaimed temporary exhibitions. On view from 11 September 2010 to 16 January 2011 in the K20 and the Schmela Haus was the ambitious Joseph Beuys exhibition "Parallelprozesse/Parallel Processes", organized around large-scale installation works dating from all creative periods of this artist. This exhibition – the first special presentation mounted after the reopening of the Kunstsammlung am Grabbeplatz – formed part of the program of the Düsseldorf Quadriennale, and was seen by 103,000 visitors. Architecture The K20 am Grabbeplatz The building which houses the Kunstsammlung K20 am Grabbeplatz, with its distinctive façade of black Bornholm granite, was opened in 1986. Working in the tradition of Arne Jacobsen, the Copenhagen architecture office of Dissing+Weitling created a building which features details typical of its time and positions the qualities of the artworks on display in the foreground. The entrance area opens onto the Grabbe Halle on the same level, the building's tallest gallery space, which features 14-metre ceilings. Used for temporary exhibitions,
