Admirers of De Stijl, and in particular of Piet Mondrian, won't want to miss the Berlage-designed Gemeentemuseum. It houses a large collection of works by neoplasticist artists and others from the late 19th century, as well as extensive exhibits of applied arts, costumes and musical instruments. Take tram 17 from CS and HS to the Statenwartier stop.
Mondrian's unfinished Victory Boogie Woogie takes pride of place (as it should: the museum paid €30 million for it), and there are also a few Picassos and other works by some of the better-known names of the 20th century.
