The Museum in the Kleihues Building is an art museum with rotating exhibitions on 20th- and 21st-century art. The range extends from classical modernism to contemporary art. Exhibitions on cultural history related to everyday culture as well as to the Salamander company and its advertising figure "Lurchi" are also part of the exhibition concept. The museum's collection comprises nearly 3,000 works, mainly German art of the 20th and 21st centuries, ranging from Max Ackermann and Otto Herbert Hajek through Royden Rabinowitch and HAP Grieshaber to Fred Thieler and Günther C. Kirchberger. The centerpiece of the collection is formed by almost 700 works by the Swabian late Impressionist Manfred Henninger (1894–1986), one of the co‑founders of the Stuttgart New Secession (1929). A collection of contemporary art is being developed with a primary focus on the artist scene in southwest Germany, as well as another collection of works by well‑known commercial graphic artists (Otto Glaser, Franz Weiss) who, in the 20th century, worked for the Kornwestheim‑based global company SALAMANDER. Since 1989 the collection has been housed in a widely noted museum building by the Berlin architect Josef Paul Kleihues. In 2017 the Museum in the Kleihues Building was added to the list of cultural monuments in Baden‑Württemberg.
