In his 56 years of service, Vauban, who was already an Ingénieur de France, designed 33 new forts, delivered over 400 projects for 160 sites and modernized countless existing forts. He is the actual creator of the enceinte de fer, the iron belt, and the pré carré, with which France under Louis XIV secured its external borders. The fortified town of Neuf-Brisach/Neu-Breisach is considered to be his main work
