The Palais Rose, located at 14 Allée des Fêtes at the corner of 12 rue Diderot in Vésinet in the department of Yvelines, was built in 1899, inspired by the Grand Trianon in Versailles. In 1986 it was added to the official ISHM listing of historical monuments. The Palais Rose in Vésinet should not be confused with the “other” Palais Rose, which once stood on the Avenue Foch and was razed in the early 1970s. The two buildings did however share a number of features. Both structures were designed around 1900 in the “Grand Trianon” style. The Palais Rose in Vésinet was built for the shipowner Arthur Schweitzer. Some ten subsequent owners, including notables such as Comte Robert de Montesquiou and the Marquise Luisa Casati, contributed to the fame of this dwelling, organizing lavish receptions there. Various owners succeeded one another until the property was purchased by an individual. It was then comprehensively restored in the 2000s under the direction of Emad Khashoggi, head of COGEMAD, who was also responsible for the Château Louis XIV project in the forest of Louveciennes. History Following the sale of the Forest of Vésinet to the Société Pallu et Cie, known as the “Société des Terrains et des Eaux du Vésinet,” by the Ministre d’Etat de la Maison de l’Empereur, the shipowner Arthur Schweitzer, cousin of Dr. Albert Schweitzer, purchased two adjacent parcels overlooking the Lac des Ibis between 1899 and 1900. He commissioned a residence in the “Grand Trianon” style, which he later named the “Palais Rose.” Schweitzer and his wife had little opportunity to enjoy the property. The shipowner declared bankruptcy and the Palais Rose was sold at auction on July 19, 1906. Ratanji Jamsetji Tata, an Indian Parsi businessman, was the winning bidder. Legend has it that he funded the purchase “by selling two pearls and an emerald.” He never occupied his prize. However, there was no question of bankruptcy in his case. Having gotten no use from the building in two years, Tata agreed to part with it, selling the property to a man of letters who had instantly fallen in love with the Palais Rose. In 1908, the poet Robert de Montesquiou first saw the house and declared: “If this house – which is not for sale and which my modest means would never allow me to buy – if this improbable, impossible, and nevertheless real house isn’t mine
