The Fortress of Mornas is a fortified medieval site perched on a sheer limestone cliff overlooking the Rhône Valley in southern France. Originally constructed in the 11th century, the structure served as a strategic military stronghold controlling the river passage. The site features extensive defensive walls, a command post, and an underground cistern carved directly into the rock. Visitors can explore the interior ruins and the ramparts that offer 360-degree views of the surrounding Vaucluse landscape.
