Thus, Italians created in 1530 a fortification new design; fortified towns whose very thick bastions could resist against these new lethal fires appeared. The fortified city was born.
The French theorists took up these principles by amending them; Vauban kept going and improved considerably the fortification’s defence and attack systems.
Vauban worked in Bazoches, his family residence, and fitted out a significant part of the Château into a research department with his engineers. He used this word to give a name to a new service he created, the Engineers.
Thus, the bigger part of these fortified towns and military works disseminated all over France were conceived, perfected and illustrated by pictures and plans in Bazoches.
With a little imagination, the exuberant activity that might exist in the Château great gallery can easily be visualized. Vauban’s instructions left, after examination, this gallery, lately reconstructed to its initial surface. Horse vans were continually ready to reach every corner of the world, bringing in cylindrical metal cases Vauban’s plans and orders.
