The Duke of Burgundy and the Palace of Government are the residences of the Dukes of Burgundy. The project was completed only in the 19th century. The western wing of the reformed palace serves as the office of the municipal government, while the eastern wing is an art gallery. Established in 1799, the Eastern Wing Art Museum of the Palace is one of the largest museums in France, with a large collection of art treasures. The gallery is open from 10:00 to 18:00, Tuesday and holidays. Sunday is free.
