The fortress was built on a barren plateau at the confluence of the Guil and Durance rivers to control the valley access.
Despite being one of Vauban's largest projects, the fortress was never completed as originally designed due to changing geopolitical tensions.
The pink Eygliers marble used for construction is a type of limestone that hardens when exposed to air.
The village square features a dry well that was intended to be the center of an elaborate water collection system that was never fully realized.
The Church of Saint-Louis, located within the walls, remains unfinished, with its facade displaying the rough stone left by original masons.
Mont-Dauphin is an 18th-century fortified village built by Vauban under orders from Louis XIV to defend the French border against the Duchy of Savoy. It is designated as a UNESCO World Heritage site as part of the 'Fortifications of Vauban' series. The town is constructed entirely of pink marble quarried from the nearby town of Eygliers. The fortress was designed as a 'place neuve,' a planned military town intended to house 2,000 soldiers and their families. It remains one of the few examples of a bastioned village that was never captured by enemy forces. The site features original military barracks, an arsenal, and a powder magazine that remain largely unchanged in external appearance. It serves as an active residential village, distinguishing it from traditional open-air museums. The geometric layout exemplifies classical military urbanism designed for defensive efficiency.

Wear sturdy walking shoes as the village streets are paved with original stones that can be uneven.
Bring a jacket even in summer, as the plateau's altitude causes rapid temperature drops in the evening.
Explore the grassy ramparts for a 360-degree view of the surrounding Ecrins and Queyras mountain ranges.
Do not attempt to climb or traverse the military walls outside of designated paths, as the masonry can be unstable.
Some exhibition spaces and museums within the fort have limited access during the winter months.
Respect the privacy of residents; the village is a living community, not just a historical site.
