Château de Crussol is a 13th-century fortress ruin situated on a limestone cliff overlooking the Rhône Valley. The site comprises the remains of a fortified village and a central keep, once controlled by the Crussol family. It sits at an elevation of approximately 200 meters above the town of Saint-Péray. The ruins occupy a strategic position that historically dominated the river trade routes. Visitors can explore the archaeological remnants via marked trails that wind through the former village streets. Erosion and rockfall risks have led to restricted access zones within the site perimeter. The site remains a protected heritage area managed for conservation and historical interpretation.
