The Museum of Decorative Arts of Milan constitutes one of the most relevant collections of this type existing in Italy. It is located in the Sforza Castle, in some of the rooms of the Ducal Court and on the second floor of the Rocchetta.

The Museum of Decorative Arts documents the evolution of taste and styles in sumptuary, decorative, and applied arts from the early Christian era to the 1950s, reaching the 21st century regarding artistic glassware.

Along the exhibition path, masterpieces and exceptional artifacts succeed each other in terms of quality, precious documents of the work of glassmakers, ceramists, carvers, luthiers, silversmiths, goldsmiths, gunsmiths, tapestry weavers, and textile workers active in Europe since the Middle Ages. The collection includes tapestries, weapons, ivories, bronzes, ceramics, leathers, wrought irons, majolica, goldsmithing, clocks, porcelains, enamels, textiles, scientific instruments, glasses. The weapons and some tapestries are exhibited in the first rooms of the Ducal Court; the second floor of the so-called Rocchetta is instead entirely dedicated to applied arts.
