After the bishops, the palace had many lives. During the French Revolution it served as a place of detention. Then, on 21 December 1794, the solemn opening of a military health officers' school in Strasbourg took place, with its classes held here in the palace. The next change came after the German annexation of Strasbourg. Between 1872 and 1884 the palace housed the faculties of law, philosophy and sciences of the newly established Kaiser-Wilhelms-Universität, until the Palais universitaire opened. Since the end of the nineteenth century, it has been home to museums: the Archaeological Museum in the basement, the Museum of Decorative Arts on the ground floor, and the Museum of Fine Arts on the first and second floors. The Galerie Robert Heitz, in a lateral wing, hosts temporary exhibitions. The palace has been a listed historic monument since 1920. It was restored after the bombings of 1944, and it still receives distinguished guests. On 3 April 2009, during the North Atlantic Treaty Organization summit, it hosted the first meeting between French President Nicolas Sarkozy and the newly elected American President Barack Obama.
