The Palais Mazarin (Mazarin Palace) was created by Mazarin beginning in 1643, soon after he became first minister, when he rented four adjacent "hôtels" on the north side of the Rue Neuve-des-Petits-Champs between the Rue Vivienne to the east and the Rue de Richelieu on the west and across from the Palais Royal, which was the King's residence. He commissioned François Mansart to add a garden wing with two superimposed galleries running north from the west end of the easternmost building, the Hôtel Tubeuf, where he could display his art. Between 1645 and 1647 he commissioned the Italian painter Giovanni Francesco Romanelli to create scenes from the works of Ovid on the ceiling of the upper gallery (although much modified, now known as the Galerie Mazarine). In 1721, the Palais Mazarin became the site of the King's Library (Bibliothèque du Roi), now the Richelieu site of the Bibliothèque nationale de France. Mazarin spent little time in his Palace; he lived most of the time in the Palais Royal, when Louis XIV was in residence there, or in the Louvre. Near the end of his life he resided in the Château de Vincennes, where he decorated a suite of rooms. He also had the moats of the chateau turned into a kind of zoo, with lions, tigers, bears and other exotic animals, for the amusement of the young King.
