The castle houses the municipal museum, which consists of two important collections.
One is devoted to the decorative arts from the Middle Ages to the 18th century. The bequest in 1919 by Count Charles Lair of his own collection thus enriched that of the municipal museum and allows the museum to present one of the most beautiful collections of decorative arts in France. It includes furniture, paintings, exceptional tapestries (from the 15th to the 18th century), and one of the richest collections of ceramics in France, covering most of the major centres of earthenware and porcelain production (from the 16th to the early 19th century).
Visitors will be able to discover Nevers with Italian, Persian, Chinese or popular designs, Rouens with shimmering decorations, and Moustiers inspired by the engravings of Bérain and Jacques Callot for the French "grand feu" productions. The flowers of Strasbourg, the trompe-l'oeil of Nidervillier, the rural scenes of Marseille and the birds of Sceaux testify to the diversity of the decorations of the "petit feu". Also on display are soft porcelains from Rouen, Saint-Cloud, Chantilly, Mennecy and Vincennes-Sèvres. Finally, foreign pieces are there to show us the reciprocal influences.
The collection also includes an exceptional set of tapestries. Secular or religious subjects also characterize this collection which borrows from history its most famous representations. Historical subjects, such as the tapestry La Vengeance de Notre-Seigneur (The Revenge of Our Lord), which came out of the workshops in Tournai in the 15th century, are displayed alongside 18th century representations of the Gobelins' children gardeners. The most enigmatic is without a doubt the continuation of the Savages, composed of the Bal des Sauvages and the Fight of the Knights and Wild Men.
