Biography
Sébastien Le Prestre de Vauban was a man of the earth who became the shield of the Sun King. Rising from a modest background through sheer talent, he spent his life in the mud and dust of construction sites and battlefields. As Louis XIV's chief military engineer, he did not just build forts; he designed an entire defensive system—a 'ceinture de fer' (iron belt) of over 300 citadels that projected French power. His genius was dual: he made fortresses nearly impregnable with his signature star-shaped bastions, and then wrote the rulebook on how to systematically demolish them. A pragmatic innovator, he also conducted early statistical surveys of French resources. Vauban was ultimately a servant of the state, but his legacy is set in stone across the European landscape.
