Hôtel Perrinet de Jars, Protected heritage mansion in 8th arrondissement, France.

Hôtel Perrinet de Jars stands at 33 rue du Faubourg-Saint-Honoré, its pale stone facade grooved in horizontal bands across several storeys. Seven windows pierce the upper floors, four with dark glazing and black railings; a projecting porch on columns carries a triangular pediment above a dark wooden door, with a black lantern on a curved bracket beside it. The street building was raised in 1928.

Built in 1714 by Pierre Grandhomme for Anne Le Vieux, wife of financier André Le Vieux, the hôtel took its name from fermier général Étienne Perrinet de Jars, who had Jean-Michel Chevotet transform it. Denis, Duke of Decrès, Napoleon's Navy Minister, bought it in 1810; from 1849 it was rented to the Russian embassy. Baron Nathaniel de Rothschild acquired it in 1856 for FF 1,675,000 and had it rebuilt around 1864, reusing 1762 woodwork by Étienne-Louis Boullée from the hôtel de Tourolle. Listed as a monument historique on 13 April 1928.

The building hosts the Cercle de l'Union interalliée, a private club founded after World War I to bring together officers from Allied nations. The space reflects the importance of international cooperation and military bonds in Parisian society.

The building operates as a private club with restricted access, requiring advance arrangements or membership for entry. It is best to contact the current operators beforehand to inquire about possible visiting options.

The panelling inside was made in 1762 by Étienne-Louis Boullée for the hôtel de Tourolle on rue Charlot, then moved here during Léon Ohnet's 1864 rebuilding for Baron Nathaniel de Rothschild. Nathaniel had bought the mansion in 1856 for FF 1,675,000 and kept his Old Master paintings, 18th-century furniture, manuscripts and books there.
