Château de Montaillou, Medieval castle in Montaillou, France.
The castle remains feature three walls of the keep and a platform measuring 100 meters in length and 40 meters in width.
In 1638, Louis XIII ordered the demolition of the castle, which had previously served as a frontier fortress between the County of Foix and neighboring territories.
The castle was central to the investigation of Catharism by Jacques Fournier, whose detailed records are now preserved in the Vatican archives.
The archaeological site is open year-round with no entrance fee, but visitors should exercise caution due to the unstable ruins and uneven terrain.
The castle's defensive system combines dry moats carved into rock on the northern and eastern sides with natural slope protection on the southern side.
