Forteresse de Mornas

Forteresse de Mornas sits on a limestone cliff about 150 meters above the Rhône and spreads across a large area with multiple building rows. The complex features a strong central keep, various living quarters, and fortification walls that take advantage of the natural slope of the rock.

The fortress was built in the 11th century as a control point for the Rhône Valley and repeatedly changed hands between the Counts of Toulouse and the Archbishopric of Arles. Different rulers expanded and reinforced the walls over the centuries depending on who held power at the time.

The name comes from the Mornas family who ruled the area for centuries, and this heritage shapes how locals view the site. Walking through the ruins, you notice how the buildings were designed to house soldiers and nobility who managed the surrounding region.

The site is best visited on clear days when views of the surrounding mountains and valleys are especially good. The climb requires sturdy shoes since there is uneven ground, but the paths are generally accessible and well-marked throughout.

The central keep rises about 20 meters high and offers a wide panoramic view over the entire Rhône Valley from its top. From this vantage point, visitors can see Mont-Ventoux and the jagged peaks of the Dentelles de Montmirail on clear days.
