Hôtel de La Rochefoucauld-Doudeauville, Private mansion in 7th arrondissement of Paris, France.

The Hôtel de La Rochefoucauld-Doudeauville is a pale stone neoclassical mansion at 47-49 Rue de Varenne, built around a paved courtyard with two perpendicular wings and a black mansard roof with dormer windows. Round-arched ground-floor windows and doors with fanlights sit between pilasters, while the first floor has tall windows with wrought-iron balconies. A short stone stair leads to the central entrance, and a projecting gatehouse with carved stonework frames tall dark-green doors.

Jean-Sylvain Cartaud built the hôtel in 1732 for Gérard Heusch de Janvry, secretary to the king, on land leased from the religious of the Charité. Henri Parent transformed it from 1876 for the Duke of Bisaccia: the upper floor was raised, the courtyard and garden facades reworked and the roof rebuilt, with work inaugurated in 1888. The Caisse des dépôts et consignations bought it in 1937, and since 1938 it has housed the Italian embassy under an exchange with the Palazzo Farnese in Rome. Facades and several interior decors were inscribed as monuments historiques by decree of 11 June 1926.

The building's name recalls the Boisgelin family, whose cardinal, Raymond de Boisgelin, archbishop of Aix-en-Provence, occupied it from 1782. Since 1938 it has housed the Italian embassy, and its dining room and theatre were redecorated by Adolfo Loewi with a ceiling and panels by Francesco Guardi from Palazzo Mocenigo in Venice and woodwork from a Palermo palace.

The mansion is located at 47 Rue de Varenne in the 7th arrondissement and is not open to the public due to its private status. You can view the exterior facades from the street, but access to the courtyard and interior is restricted.

The interior rooms contain original decorative elements from multiple different periods, layered throughout the residence. This reveals how successive residents updated and modified the spaces over generations without erasing earlier designs.
