L'Hotel de Broglie

In 1782, it was remodelled/rebuilt for the Marshal de Broglie by the architect Jean-Baptiste Louis Élisabeth Le Boursier. It was acquired by the Marquis de Semonville who rented it from 1815 to the Duke of Plaisance whose eldest daughter-in-law was the Philadelphia-born, Sophie de Barbe-Marbois. In 1826, it was bought by the widowed Duchess of Montebello (1782-1856). After her death, it again underwent a grand transformation for the new owners, the Comte d'Haussonville, and his wife the essayist Louise de Broglie (1818-1882), to the designs of Gabriel-Hippolyte Destailleur.

In 1914, it became one of the five residences of the American couple Ogden Mills and his wife, Ruth. From 1917 to 1920, they leant it to the U.S. government as the Headquarters of the US Army. It passed to their daughter, Beatrice, Countess of Granard, when it became known as the "Hotel de Lord Granard" for her Irish husband. Using Jacques Robine, Beatrice restored the old house in 1970, and died two years later. Today, it is one of the residences of King Mohammad VI of Morocco. Sitting in its own courtyard, its splendor is concealed from the street by an imposing gated wall.
