For the neoclassical palace of the Prince, the entrance on rue Université was replaced by a larger and more impressive gate, framed by a gallery of columns. The two wings of the building were extended, and a pavilion was created with apartments for one of his sons. An abundance of military decoration, including stucco sculptures of shields and weapons, was added to the vestibule, and are still visible today. The palace was only finished at the end of the 1780s, when the French Revolution swept away the old regime. The Prince went into exile, and the two residences were confiscated by the state in 1792.
