Vauban fortifications are a type of military defensive structures designed by the French military engineer, Sébastien Le Prestre de Vauban, in the 17th century. These fortifications were characterized by their innovative and strategic design, which aimed to maximize the defensive capabilities of a fortress while minimizing the resources and manpower required for its construction and maintenance. Vauban fortifications often featured star-shaped layouts, bastions, and moats, and were widely used in Europe during the late 17th and 18th centuries. They were considered highly effective in defending against enemy attacks and played a significant role in shaping the military architecture of the time. **

Instead, they relied on their knowledge of the land, their skills in warfare, and their ability to adapt to different environments for protection. **
