A famous collection of European paintings from the 13th to the 19th centuries, the Wallraf-Richartz-Museum occupies a postmodern cube designed by the late OM Ungers. Works are presented chronologically, with the oldest on the 1st floor where standouts include brilliant examples from the Cologne School, known for its distinctive use of colour. The most famous painting is Stefan Lochner's Madonna of the Rose Bower.
Upstairs are Dutch and Flemish artists, including Rembrandt and Rubens, Italians such as Canaletto and Spaniards such as Murillo. The top floor shines the spotlight on the 19th century with Germany's largest collection of impressionist paintings, including masterpieces by Monet, Van Gogh, Cezanne, Gauguin and all the other heavy hitters of the genre.
