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.
