The underground fortress of Château de Brézé, nestled in the Loire Valley in France, is a historic gem that uniquely combines the superficial elegance of a traditional castle with a vast and complex underground complex. Dating back to the 11th century, the castle’s current form mainly reflects the 16th and 19th centuries.
It is renowned for its vast underground fortress, which extends up to 18 meters below the surface, exceeding the castle’s above-ground size. This underground labyrinth includes functional spaces such as kitchens, bakeries, and even private apartments, as well as defensive features such as loopholes for archers, emphasizing its role as a refuge and fortification.
