Built at the end of the 12th century by the Counts of Montfort and listed as a Historic Monument since 1889, the Houdan Tower was used to watch for enemies and defend the territory. The Keep consists of a 15 m diameter and 21 m high tower, flanked by four turrets of the same height located at the four cardinal points. From the 16th century until the French Revolution, the Keep served as a prison, and executions took place at the foot of the Tower. The first water reservoir was installed in the tower in 1880. The second, built in 1952, is still visible. Tours are available on certain days.

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.
