Musée de Cluny, in Paris, museum of arts and crafts from the Middle Ages, including the Hôtel de Cluny, which houses the collection, and the adjoining Thermes de Cluny ancient thermal baths.

The Hôtel de Cluny was built in the Gothic style in 1485 as the town residence of the abbots of Cluny. It was constructed next to the ancient Gallo-Roman public baths. Alexandre du Sommerard, owner of the mansion from 1833, assembled a collection that later became the basis of the museum. The French government acquired the property and collection on du Sommerard’s death in 1842 and in the following decades restored the mansion as well as the baths and created a museum dedicated to the art of the Middle Ages and the preservation and exhibition of the ancient baths. The collection was reorganized in the early 1950s to present a coherent history of medieval civilization and includes gold- and silverwork, stained glass, sculpture, jewelry, textiles, and everyday articles. In 2015 the museum began a multistage restoration, which included construction of a new reception area, and it reopened fully in 2022.
