Hôtel de Chaulnes

The Hôtel de Chaulnes is a historic mansion on the Place des Vosges in Paris's 4th arrondissement, situated between the Hôtel de Sully and the Hôtel de Pierrard. Originally built in the early 17th century, it changed hands several times before the third Duke of Chaulnes had the right wing extended by Jules Hardouin-Mansart. Over the years, the property served various noble families and, among others, was home to the famous actress Rachel. Today the building is partially protected, with the facade and the vaulted gallery classified as historic monuments. The second floor currently houses the headquarters of the Académie d'architecture, lending the site cultural and architectural significance.
