Yet another standout art collection, designed by Berlin architects Hascher and Jehle, is housed in a filigree glass cube surrounding a rough-hewn limestone inner core. Taking center stage are 19th- and 20th-century works by artists from southern Germany; the paintings, many depicting the brutality of war, by Otto Dix (1891–1969) are particularly compelling. Many of his works were burned by the Nazis, though some of them were hidden by an art dealer and not uncovered until 2012. The museum was highly supportive of Dix in the post-war years and has the most important collection of his works in the world. If you’re wondering what the fuss is all about, check out his “Gross Stadt” (“Big City”) triptych, depicting decadent urbane life in the 1920s. The top floor, a cafe open to the public, provides a panoramic view of Stuttgart and its surrounding hills.
