The Palais Rohan in Strasbourg is the former residence of the prince-bishops and cardinals of the House of Rohan, an ancient French noble family originally from Brittany. It is a major architectural, historical, and cultural landmark in the city. It was built next to Strasbourg Cathedral in the 1730s, from designs by Robert de Cotte, and is considered a masterpiece of French Baroque architecture. Since its completion in 1742, the palace has hosted a number of French monarchs such as Louis XV, Marie Antoinette, Napoleon and Joséphine, and Charles X.
Reflecting the history of Strasbourg and of France, the palace has been owned successively by the nobility, the municipality, the monarchy, the state, the university, and the municipality again. Its architectural conception and its iconography were intended to indicate the return of Roman Catholicism to the city, which had been dominated by Protestantism for the previous two centuries. Thus the prelate's apartments face the cathedral, to the north, and many of the statues, reliefs and paintings reflect the Catholic dogma.Since the end of the 19th century the palace has been home to three of Strasbourg's most important museums: the Archaeological Museum , the Museum of Decorative Arts and the Museum of Fine Arts . The municipal art gallery, Galerie Robert Heitz, in a lateral wing of the palace, is used for temporary exhibitions. The Palais Rohan has been listed since 1920 as a Monument historique by the French Ministry of Culture.
