Hôtel de Gramont, Private mansion on Place Vendôme, 1st arrondissement, Paris, France

The Hôtel de Gramont is a private mansion on Place Vendôme in Paris, designed by Pierre Bullet using classical French architectural elements in stone construction. Its facade displays the characteristic symmetrical composition and refined details typical of this prestigious Parisian address.

The plot was bought in 1705 by Antoine Bitault de Vaillé for Anne Baillet de La Cour, who had Pierre Bullet build the mansion from 1708 to 1710; she married Duke Antoine-Charles de Gramont that year. John Law rented it in 1714, and in 1721 the widowed duchess sold it to the Count of Lautrec. César Ritz bought it in 1897 and Charles Mewès converted it, opening as the Ritz on 1 June 1898.

The name comes from Anne Baillet de La Cour, who had the mansion built and married Duke Antoine-Charles de Gramont in 1710. In 1721 the young Louis XV watched the Turkish ambassador's procession from a first-floor salon. Since 1898 the building has operated as the Ritz Paris, and its first-floor salon, study and boudoir were listed in 1927.

The building stands at no. 15 on the west side of Place Vendôme, between the Hôtel de Bourvallais at no. 13 and the Hôtel Crozat at no. 17. It is now part of the Ritz Paris, so the five-level facade with its mansard roof and round dormer windows is seen from the square; the entrance sits behind iron gates.

The 1927 listing covers the first-floor salon, cabinet and boudoir, while the 1930 decree classifies the facades and roofs. The two dates therefore protect different parts of the building, not two levels of the same status.
