Hôtel de Crillon, A Rosewood Hotel

Louis XV had Ange-Jacques Gabriel raise two identical facades either side of the rue Royale in 1758. The ground behind the western one was cut into four lots and sold to private buyers who had to build behind Gabriel's front. Louis-François Trouard bought the westernmost in 1775 and drew the house himself. François Félix de Crillon bought it as a family home in 1788, and it opened as a hotel in March 1909. The colonnade and the sculpted front are classified, the higher of the two French heritage grades.

Rosewood reopened it on 5 July 2017 after four years of work. Richard Martinet ran the architecture under heritage protection covering the facade and the second-floor reception rooms, while Aline Asmar d'Amman took artistic direction. The job ran to 250 artisans across 147 separate crafts, 53 varieties of marble, and 17,000 cubic metres excavated from under the building. There are 78 rooms, 36 suites and ten signature suites.

Karl Lagerfeld decorated the two on the fourth floor facing the Concorde, and Chahan Minassian put the three Ateliers d'Artistes under the mansard roof in what were once the administrative offices. Upstairs the listed salons keep ceilings from 1775 and 1776 that clear six metres. The Salon des Aigles is where the Covenant of the League of Nations was drafted through the winter of 1919, though the signing itself happened at Versailles that June.
