This is one of the most comprehensive and finest museums in the region. The brilliantly devised museography showcases top-notch collections. It is located in two mansions: Hôtel Dufraisse (1709) is home to the collections of painting, design and decorative arts; Hôtel Desaix exhibits the Donation Richard, former President of the Bar. This great collector of works of art is the initiator of the museum and instigator of its restoration.
