Not far from the route, this unusual little chapel, perched on the promontory of Le Châtelard at an altitude of 1,450m, enjoys an incredible view over the Haute-Tarentaise valley. A special viewing system using metal tubes means you can observe the summits and villages up the mountainside from the River Isère all the way to the Haute-Tarentaise ski resorts. This chapel is dedicated to the Archangel Michael, the patron saint of high places.
