This feudal castle, above the Rhone valley, has long been a sentinel of the county of Provence facing the Kingdom of France. Dating from the 11th century, it belonged to different owners, some of whom have left their names in history, like Raymond de Turenne or King René. The last Count of Boulbon, Gaston de Raousset, died in Boulbon without direct descendants in 1956. The castle is classified on the list of Historical Monuments since a decree of January 2nd, 1976.
