Deutsches Tapetenmuseum, Wallpaper museum in Kassel, Germany

The Deutsches Tapetenmuseum is a Kassel museum devoted to wallpaper and room decoration, founded in 1923 and part of Hessen Kassel Heritage since 1993. Its collection of over 23,000 wallpapers ranges from 16th-century gilt-leather hangings and Chinese papers to contemporary designer prints, including 41 of the roughly 90 known panoramic wallpaper designs. Since 2008 the holdings have been kept in storage and shown in temporary exhibitions; a new building at Brüder-Grimm-Platz, incorporating the Nördliche Torwache, is under construction.

The Deutsches Tapetenmuseum opened on 30 June 1923 in the Rotes Palais on Friedrichsplatz, founded by the association initiated by wallpaper dealer Gustav Iven. In the night of 8–9 September 1941 an air raid destroyed the Rotes and Weisses Palais and parts of the collection; around 6,000 wallpapers were saved and stored at six sites. The museum reopened in 1948 in the Weissstein wing of Schloss Wilhelmshöhe, moved to the Hessisches Landesmuseum in 1976, and closed there in 2008.

The collection shows how people's taste in home decoration changed across different periods. You can see in the patterns and colors what was considered beautiful and fashionable in each era.

The museum has been closed to the public since 2008, when the Hessian State Museum closed for renovation; parts of the collection have since appeared only in temporary exhibitions. A new building is under construction at Brüder-Grimm-Platz opposite the state museum, on the site of the former Hessian Administrative Court, incorporating the Northern Gatehouse. The cornerstone was laid on 30 June 2023, and the opening, first planned for 2026, has been pushed back to autumn 2027.

The collection's best-known piece is a French panoramic wallpaper of the 1820s depicting the Battle of Austerlitz. Of roughly 90 known panoramic wallpaper designs, 41 are held in Kassel. The museum also keeps Biedermeier wallpapers by Johann-Christian Arnold, who opened one of Germany's first wallpaper manufactories near the future museum site in the 1790s.
