The Île Saint-Louis was still being built when, around 1656, Charles Gruyn, the son of a prosperous innkeeper who had made his own fortune as a commissioner of the cavalry during the Fronde, commissioned a house on the quai d’Anjou. The architect was Charles Chamois, who worked in the circle of Louis Le Vau, the island’s leading builder. The plain stone front, with its long gilded iron balcony and carved gutters, gives little away. Inside, every surface of the first-floor rooms was painted, carved and gilded, and Gruyn’s initial was twined with his wife’s. When his patron, the finance minister Fouquet, fell in 1661, Gruyn fell with him, convicted of fraud.
The house takes its name from a later owner, the Duke of Lauzun, a courtier of Louis XIV famous for his insolence, his imprisonments and his romance with the king’s cousin, the Grande Mademoiselle. He stayed only a few years. In the eighteenth century the house declined into lodgings and workshops, until in 1842 the bibliophile Baron Jérôme Pichon bought and restored it.
Pichon let rooms. From October 1843 to September 1845 the young Charles Baudelaire, not yet published, lived under the roof, spending what was left of his inheritance on clothes and pictures. Below lived the painter Fernand Boissard, and in his rooms from 1844 Théophile Gautier and others met for the monthly sessions of the Club des Haschischins, where guests ate a green paste of hashish and wrote about what followed. Gautier gave an account of it in 1846, Baudelaire later in Les Paradis artificiels. Accounts that Balzac, Delacroix or Hugo attended are less secure.
Listed as a historic monument in 1906, the house was bought by the City of Paris in 1928 and used for receptions and concerts. Since 2013 it has been home to the Paris Institute for Advanced Study, which hosts visiting researchers. According to the City of Paris, it is closed to the public until further notice.
What to look for
- The long gilded wrought-iron balcony on the quai d’Anjou.
- The carved seventeenth-century gutters on the façade.
- The sundial-like meridian on the north wall, out of use since its perforated disc was removed in 1957.
- The view across the Seine from the quai, as Baudelaire would have had it from his attic.
