The German artist Thomas Schütte asked: “What do you do with the stuff when you’re dead?” His answer: build a museum to house it. Due to open on 10 April, the 700-sq.-m sculpture hall in the grounds of the Museum Island Hombroich, near Düsseldorf, will show work by international artists as well as Schütte’s own. Although architectural models are a key part of Schütte’s output, the museum is his largest and most ambitious building to date. Its design is based on a sketch of a matchbox topped with a potato crisp. The €4.5m project is supported by the newly established Thomas Schütte Foundation. Its inaugural exhibition is dedicated to the Italian Arte Povera artist Mario Merz.
