This fortress dominates the town of Mornas below, rising up from the 137 metre tall cliffs.
Discover more about its history in a guided tour (in French) or wander around the old ramparts and reconstructed Medieval buildings.
The guides are all dressed in Medieval costumes, some with swords and shields and some play fighting with each other to try and bring the Medieval period back to life. It's a great stop off for children or adults.
The views from the top are amazing on a clear day with Mont Ventoux, les Dentelles de Montmirail and the Rhone Valley stretching out in front of you.
Adults 5 euros, children 3 euros.
