The Tower (commonly called "The Dungeon"), built in the 12th century under the reign of the Counts of Montfort, and classified as a Historic Monument since 1840, had the function of watching out for enemies and defending the territory. But in reality, it mainly had a dissuasive role since it was reputed to be impregnable. Built on the site of an old Merovingian necropolis, it originally consisted of an enclosure and a main tower. The enclosure, which has now disappeared, had a circular turret intended for the defense of the gate. The access door, located 4 meters from the ground then raised in the 15th century to 6 meters, was the only access to the large room on the 1st floor reserved for the military chief. It was accessed via a drawbridge.
