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.
