Mont-Louis Citadel, perched high in the Pyrenees, is a testament to the military genius of Sébastien Le Prestre de Vauban, the renowned military engineer of Louis XIV.

Exploring the citadel, you'll discover well-preserved ramparts, barracks, and the oldest solar furnace in the world, still in operation. The citadel's design reflects Vauban's innovative approach to defensive architecture, incorporating geometric patterns and strategic placement to maximize firepower and minimize vulnerability. Walking along the ramparts, you can appreciate the panoramic views of the surrounding mountains and valleys, offering a sense of the strategic importance of this location. Mont-Louis is not just a historical monument; it's a living community, with shops, restaurants, and homes nestled within its ancient walls.
