Redoubt

This tower was probably necessary to fortify the castle during the Hundred Years' War. Its extremely thick walls (1.7 m as compared to 80 cm for the residence) reinforce a corner of the castle wall and served as the last line of defence. They follow the contours of the vertical cliffs. The tower still shows the vestiges of three corbels just above the access door, which must once have supported a bretèche (small defensive balcony). Inside, the floors separated by vaulted ceilings are accessible through manholes.
