Coulonges, a Defensive Fortress
It was through the sound of the olifant or by smoke signals that the Lordship of Montignac was alerted of the arrival of enemy troops in less than a quarter of an hour, thanks to the protective belt formed by Coulonges Castle connected to a circle of watchtowers. At the initiative of the medieval researcher Bernard Fournioux, exercises conducted by the Army confirmed the effectiveness of this ingenious defensive system from the Early Middle Ages.
