Hôtel de Mademoiselle Mars, Historical monument in the 9th arrondissement, France.

Hôtel de Mademoiselle Mars is a private mansion located at the intersection of Rue de la Tour-des-Dames and Rue La Rochefoucauld with characteristic early 19th-century architecture. The building displays elegant proportions, ornamental stucco columns, and handcrafted details that showcase its period design.

Louis Visconti built the mansion in 1820 for Marshal de Gouvion-Saint-Cyr, on land the marshal had bought from receiver general Augustin Lapeyrière. In 1824 Gouvion-Saint-Cyr sold it to Mademoiselle Mars, the actress who gave the house its name. The building has been inscribed as a monument historique since 30 December 1977.

The mansion bears the name of Mademoiselle Mars, the actress who bought it in 1824 and lived there until her death in 1847. The name recalls the theatrical world of the 9th arrondissement, where the rue de la Tour-des-Dames was home to several performers of the period.

The building is located in the 9th arrondissement in an easily accessible area with good street connectivity. Visitors should note that it remains a private residence, so viewing the exterior is the recommended option.

The 1985 restoration by architect Michel Mimran recreated the façades, roof, hand-painted wallpapers and stucco columns of the entrance hall using traditional methods. Look for the small blue plaque with the white numeral 1 between the upper floors on the right of the façade.
