French fortification system

The French fortification system was a strategic defense network developed to protect against invasions, especially along borders like the east and north. It included a series of forts, walls, and defensive structures designed to absorb attacks and slow enemy advances. Notably, the Séré de Rivières system (late 1800s) used modern artillery-proof forts placed at key points, interconnected by trenches and fortified positions, creating a layered defense. The system aimed to maximize terrain advantage, with thick walls, reinforced artillery emplacements, and communication lines, enabling France to defend its territory effectively during periods of conflict.
