Hôtel de Nevers (rue de Richelieu)
The Hôtel de Nevers was an aristocratic townhouse in Paris, which was located on the right bank on the east side of the rue de Richelieu. It was earlier part of Jules Mazarin's Palais Mazarin, but upon his death in 1661, the palace was divided among his heirs, and the western section along the rue de Richelieu became the Hôtel de Nevers. In 1721 it was incorporated into the Bibliothèque du Roi. With the growth of the library collections, the Hôtel de Nevers became inadequate for its purpose. Most of the original Hôtel de Nevers was obliterated in 1859, after Napoleon III asked the architect Henri Labrouste to remodel and extensively rebuild the entire site. Only a remnant of the Hôtel de Nevers remains. It was declared a monument historique in 1975.
