 Between the 14th and 17th centuries the Cesana valley was damaged directly and indirectly by the wars of religion, mainly fought against the "Waldensian heretics" in the Valle Chisone.During the War of the Spanish Succession (1701-1714) the territory was attacked and conquered by French troops.In the 18th century Cesana's strategic importance declined until an era when new roads were constructed and the town once again benefited from commercial traffic.
