At the beginning of the 1930s, tourists staying in the Mayens of Nax became more and more numerous. Judge Eugène Ambord in Bramois felt at the time that the parish church was no longer sufficient to accommodate all summer visitors. Therefore, once the episcopal authorisation had been obtained, he decided to build a chapel in the Mayens des Baucs, on land belonging to him, which he donated to the Capuchin Fathers, as well as a chalet to accommodate them. The Capuchin Fathers came to spend their summer holidays in the chalet below the chapel. They had to provide Sunday religious services and the rosary during the summer period, which they did for 37 years, creating a very friendly and appreciated animation in the Mayens.

Due to the lack of priests and brothers in the congregation, the Capuchin fathers were no longer able to carry out their task and in 1971, according to an established convention, the chapel and the chalet were returned to the Ambord family.

In the summer of 2002, the builder's great-grandchildren took it upon themselves to restore the chapel, which was inspired by the baroque typology with its three-sided apse and its bell tower, while at the same time being restored in the country style thanks to the exclusive use of wood. The numerous openings protected by shutters and the sculpted sawtooth decoration is reminiscent of the surrounding chalets.
