Hôtel de Cassini, Private mansion in 7th arrondissement, Paris, France
The U-shaped Hôtel de Cassini features a central building with two perpendicular wings, marble floors in the vestibule, and a garden facade with mansard roof.
Claude Billard de Bélisard designed this mansion in 1771 for Marquis Dominique-Joseph de Cassini, a military officer and member of a distinguished family of astronomers.
The mansion served as a gathering place for artists and writers during the ownership of Cecil and Mimi Pecci-Blunt in the early twentieth century.
Since 1974, the building houses French government administrative services, including offices for Secretaries of State and the General Commissariat for Investment.
The courtyard facade of this Parisian mansion influenced the architectural design of two American estates: Miramar and Rose Terrace by Horace Trumbauer.
Location: 7th arrondissement of Paris
