Château de Monbadon is one of the last remaining examples of medieval military architecture in the Gironde. It was at the start of the Hundred Years' War, on 24 April 1330, that Edward III, King of England, gave “licence” to Indie de Monbadon to fortify this outpost in Guyenne in order to keep watch over the Isle and Dordogne valleys. Since 1602, under the reign of Henri IV, King of France and Navarre, the same family has owned the entire estate.
The church of Monbadon is located in a valley carved out between two hillsides, where the château of the same name stood to the east and the noble house of Jouanin to the south-west. Originally, Monbadon castle was a watchtower with the village of Saint-Martin de Bohens below.
