At first, a chapel was founded in 1438 on this place, when it was depending of La Chapelle d'Abondance. Châtel became a parish in 1643. A parish church was built in 1662, and was extended in 1848 so as to be large enough for the population and the first tourists.
There are also about twenty oratories in Châtel, called "lou perdons" in regional dialect.
Located in the heart of mountain pastures in summer and skiing area in winter, the chapel was built in the 1960s, on a rock that was called in ancient times "the wolves stone" or the "cursed stone".
The chapel is dedicated to Saint-François-de-Sales et Sainte-Jeanne-de-Chantal. It was built in 1784, to commemorate a rockslide that fortunately made no casualties. The chapel is built on a huge stone (520 m3 / 680 cu yd).
