Hôtel de Rohan-Montbazon, Private mansion in Faubourg Saint-Honoré, Paris, France.

The Hôtel de Rohan-Montbazon stands at 29 rue du Faubourg-Saint-Honoré. Its street facade, rebuilt in 1876 by architect Pierre Decloux, has a rusticated ground level with three arched openings and a pale stone upper section with tall windows and dark metal balconies. The main building was raised by three levels at that time.

Built in 1719 by architect Pierre Cailleteau, known as Lassurance, to plans by Jean-Michel Chevotet, for Louise-Julie de La Tour d'Auvergne, Princess of Montbazon, widow of François-Armand de Rohan-Guéméné. She followed her brother, the Count of Évreux, whose hôtel d'Évreux became the Élysée Palace. Michel Tannevot later added a wing with a chapel and kitchens, demolished in 1876; Pierre Decloux rebuilt the street building and raised the main block by three levels. The First Empire salon was listed as a monument historique on 7 November 1927.

The grand salon's First Empire decoration was commissioned by Marie-Madeleine Victoire Thomas, widow of Louis-Hyacinthe Raymond de Saint-Sauveur, who bought the mansion in 1792. This salon is the only part of the building listed as a monument historique, by decree of 7 November 1927.

The building is a private co-ownership and houses the BMH law firm, so it is not open to visitors. From the street you can see the rusticated ground floor with three arched openings and the storefront marked "by Thierry Marcovici" at the right. The First Empire salon, listed as a monument historique in 1927, is not visible from outside.

From 1922 to 1934, Gabrielle Chanel rented the ground floor and first floor of the garden-facing main building. There she received Igor Stravinsky, Pablo Picasso, José Maria Sert and his wife Misia, and art critic Serge de Diaghilev.
