Citadelle d'Entrevaux

Citadelle d'Entrevaux is a fortress perched on a rocky hill approximately 156 meters above the village. The structure combines high stone walls with multiple bastions and was redesigned by Vauban in 1690 following new military engineering principles.

Entrevaux became a royal French territory in 1536 after its inhabitants revolted against Holy Roman Empire rule. This status made the fortress a critical frontier outpost, which Vauban later modernized to reflect military developments.

The fortress displays construction methods from different periods, from medieval dungeons to baroque fortifications built in the 17th century. Visitors can see today how these different layers of history are visible in the stone walls and rooms stacked upon each other.

Access to the fortress follows a path with multiple stair structures that requires about 30 minutes of walking. The terrain is uneven and partly steep, so sturdy footwear and reasonable fitness are necessary for the climb.

During World War I, the fortress served as a prison for German officers. This marked its final use as a military installation after centuries of defensive operations.
