Fort Chailluz, Fortress in Besançon, France
Fort Chailluz is a military fortress located in the Chailluz forest area near Besançon at an elevated position. The structure follows a rectangular design that incorporates the various functional areas characteristic of 19th-century fortified installations.
This fortress was built between 1875 and 1878 as part of the first phase of Besançon's defensive fortification program. It served to protect the passage toward the Thise region and formed a key part of the military strategy of that era.
Locals refer to this fortress by the nickname 'Fort de la Dame Blanche' based on regional folklore about a white lady associated with the location. This alternative name has become deeply embedded in how people speak about the site and reflects its connection to local storytelling traditions.
Access to the fort itself is not available due to structural concerns that keep it closed to visitors. However, you can explore the nearby defensive batteries at La Fourche and La Charrière, which are open and offer views of similar military installations from the same period.
A decree issued in 1887 renamed the fortress in honor of a military commander who had died in a major European conflict more than seven decades earlier. This later renaming connects the site to a significant historical figure whose legacy has largely faded from modern memory.
