Indeed, the lock is a landmark for gray herons and cormorants. And if you take the time you may also see the blue and orange reflections of kingfishers swirling around the Doubs river.

Citadel of Besançon
Highlight • Viewpoint
Construction of the Citadelle began in 1668 under the direction of the French military engineer Vauban, known for his defense works. The fortress served as an important military stronghold and played a crucial role in the defense of France's eastern borders.
The Citadelle is a masterpiece of military architecture, with bastions, ramparts, underground tunnels and other defenses. The design reflects Vauban's innovative approaches at the time.
UNESCO World Heritage Site: The Citadelle de Besançon is part of the "Fortifications of Vauban", recognized as a World Heritage Site by UNESCO in 2008. This group of fortifications spread across France testifies to Vauban's military designs.
Within the Citadelle there are several museums and attractions, including the Museum of French Resistance and Deportation, the Comtois Museum which highlights regional history, and the Besançon Zoo, one of the oldest zoos in France.
The Citadelle offers breathtaking views over the city of Besançon and the surrounding valley. It is a popular destination for tourists due to its historical importance, architectural splendor and panoramic views.
