Chapelle Notre-Dame de Toute-Prudence

Chapelle Notre-Dame de Toute-Prudence is a chapel standing at 2,770 meters elevation on a major mountain pass. Built from local stone with a traditional roof of flat stone tiles called lauzes, it follows the construction methods of the surrounding alpine region.

This chapel was built in 1939 following the completion of the mountain pass road. The project received support from Pope Pius XI and Bishop Auguste Grumel of Maurienne, showing how religious authorities backed the development of this remote alpine area.

The chapel honors a patron saint of protection, with two statues of the Virgin Mary created by sculptor Edgar Delvaux that blend religious art with mountain traditions. Visitors can see how these works fit naturally into the alpine setting and shape the spiritual character of this high-altitude place.

The chapel is accessible to visitors during the summer season with no entrance fee. Weather at this altitude can change suddenly, so visitors should come prepared with appropriate clothing and gear.

This chapel stands on the highest mountain pass road in France, connecting two major valleys. This singular location turned the small building into a spiritual refuge for travelers crossing this demanding route.
