Hôtel de Brienne, Private mansion in 7th arrondissement, France

The Hôtel de Brienne is a private mansion in the 7th arrondissement of Paris, built in the neoclassical style with balanced facades and three full stories. Inside, it contains formal reception halls, impressive staircases, and ornate rooms that retain their original architectural character.

The mansion was constructed in 1724 by architect François Debias-Aubry and passed through several owners over time. In 1817 it became the official residence of France's Minister of Defense, a function it has maintained.

The building's name comes from Louis-Marie-Athanase de Loménie, comte de Brienne, who bought it in 1776 and was guillotined in May 1794. Under the Empire it was called "le Palais de Madame, Mère de l'Empereur" after Letizia Ramolino, who owned it from 1805 to 1817. The white marble chimney piece carved with scrolls and an eagle is among the protected fittings.

The house stands on rue Saint-Dominique, within walking distance of Solférino Metro station. Visiting is possible during the National Heritage Days each September, when the building opens to the public for guided tours.

The office of Georges Clemenceau, who directed France's victory effort from this building in 1917, had disappeared; it was recreated identically in November 2014 on the initiative of Jean-Yves Le Drian. De Gaulle's office, used from June 1940 and again from August 1944 to January 1946, has been kept as it was.
