The most important fortified mountain system in Europe
1
0
In Briançon in the Hautes-Alpes department, the morphological constraints of the terrain forced military architect Vauban to adapt. He staggered the fortifications vertically and created a belt of forts to optimize the defense of the rocky outcrop on which the town perches. The fortification of the heights dominating the city continued until the 20th century and made Briançon the most important fortified mountain system in Europe.
