Dunkirk, Toulon, Perpignan, Verdun and Brest stand out among the many historically significant sites created by Sebastien LePrestre de Vauban (1633-1707). Vauban was the foremost military engineer of France during the period of its centralisation and wars of expansion in the 17th and 18th centuries. His influence persisted long after Waterloo, and his name has become synonymous with the science of the construction, defence and attack of bastioned fortresses. This book examines the many achievements of this pivotal figure in fortification history, exploring the sites and their subsequent significance.
