Installed on the edge of the village, outside its ramparts, the castle was built between 1060 and 1090 by the Count of Albon. It was then a fortress housing a garrison whose function was to protect the Dauphiné from invasions coming from the West. It was built on a square plan, flanked by corner towers. It was then passed on by marriage to the family of Diane de Poitiers, who was born there (on January 9, 1500, the most commonly accepted date) and spent much of her childhood there. At the beginning of the 16th century, following an accusation of treason against her father by François I, the towers were levelled and their height reduced to that of the walls. In 1584, the castle became the property of the La Croix de Chevrières family who still own it today. Important works were carried out in the middle of the 18th century: filling in of the moat, construction of an orangery, creation of gardens. Nowadays, the castle is still composed of a quadrangular main building and three circular towers in angle. Although it cannot be visited, its dominant position makes it visible from many viewpoints.
