The Mondanges chapel, built in 1648, is dedicated to Saints Joseph, Hilary and Barbara.
In the years 1890-1891, the chapel was rebuilt in neo-Gothic style by the entrepreneur and architect Giuseppe Lancia.

It is characterised by its tall, slender façade with a pointed arch portal surmounted by a circular opening, large windows in the side walls and buttresses at the four corners and along the walls. The interior is marked by ribs and cross vaults.

The chapel has no bell tower, the bell is fixed to a metal frame on the roof near the façade.
The carved wooden altar is also in neo-Gothic style. The statues of the saints, once placed on the altar shelves, are now on display in the parish museum.

The Maundy Thursday procession still ends at the Mondanges chapel after vespers.

The chapel is equipped with the “Open-door church” system of automated opening and narration.
Using the dedicated app, visitors can access the chapel where a narration accompanied by images and music introduces them to of the art and sacred architecture of Valgrisenche.
