In the Middle Ages, the Château Fort de Saissac was reinforced and enlarged to become one of the largest fortresses in the region. It was then a place of residence for the local lords and a refuge place for the inhabitants of the village in the event of an attack. The fortified castle has become an important fortress for the defense of the region against enemy invasions. In the following centuries, the village of Saissac was the scene of many conflicts and wars. During the Crusades, the village was taken and taken up by the Crusaders and the Muslims. During the wars of religion, the village was taken and taken up by Catholics and Protestants. Finally, during the wars of French religion, the village was taken and taken up by the royal troops and the Protestant troops.
