| Fort Barraux, strategically positioned in the Grésivaudan valley of southeastern France, is a significant historical fortification renowned for its long and complex past. Originally constructed in the 16th century by the Duke of Savoy, Charles Emmanuel I, it was designed as a bastioned fortress, a new architectural style for the era, intended to withstand increasingly powerful artillery. Over the centuries, the fort underwent numerous transformations and improvements, notably by the famous military engineer Vauban in the late 17th century, who deeply modified its defenses to strengthen its strategic position. Fort Barraux has served various purposes, from a key border defense to a prison and even a munitions depot, before being abandoned by the military in the late 20th century. Today, this impressive structure with its extensive ramparts, ditches, and internal buildings stands as a testament to centuries of military engineering and the tumultuous history of the region
