Château d'Autet is a château located in the Luberon hills of the commune of Viens in the Vaucluse department, Provence-Alpes-Côte d'Azur, France.
Henri d'Angoulême took a major role in the two extended military battle against Huguenot strongholds during the height of the French Wars of Religion, engaging in the massive Siege of La Rochelle (1572–1573), organized by the Duke of Anjou, future Henry III of France, and leading the five-year Siege of Ménerbes (1573–1578), fought at a citadel in the Luberon foothills cherished by Pope Pius V.
There is a beautiful walk up to the Sainte Réparade chapel and, on arrival at the summit, there are panoramic views over the Durance plain, the Luberon and the Alpilles hills.
