The Palace of the Dukes and the Estates of Burgundy is the architectural heart of Dijon. The oldest parts — the Tour de Bar, the ducal kitchens, the Tour Philippe le Bon — date from the 14th and 15th centuries, when Burgundy was effectively an independent state ruling territories from the Alps to the North Sea. The 17th and 18th centuries added a Classical east wing and the broad semicircular Place de la Libération in front, designed by Hardouin-Mansart's nephew.
The palace today houses the Hôtel de Ville and the Musée des Beaux-Arts. The Tour Philippe le Bon — 46 metres, 316 steps — can be climbed in good weather for the panorama over the old town. The ducal kitchens, with their six monumental fireplaces, are open to the public free of charge.
