Perched on a rocky promontory known as “the Faucigny Lookout,” this church overlooks the Arve Valley. Built between 1829 and 1834 on the site of an older church, it is in the Sardinian neoclassical style and shaped like a Greek cross.
From this lookout point, on a clear day, you can see the Jura Mountains, the Salève, Le Môle, the Pic de Marcelly, Les Hauts Forts, the Dents du Midi, the Dents Blanches, Le Grand Ruan, Tour Sallière, the Tenneverge, Le Buet, and the Aiguille Verte.
The church of Mont-Saxonnex first appeared in historical records in 1167, when it was attached to the Abbey of Sixt, which provided its parish priests until 1636. Often destroyed and then rebuilt, it eventually became too small. Construction of a larger church took place from 1829 to 1834. The bell tower was raised in 1839. The building, in the Neoclassical style, is shaped like a Greek cross with a central plan under a dome, featuring two side chapels and a central altarpiece adorned with wooden Corinthian columns and a trompe-l’œil painted curtain.
Notable features include Baroque statues, including a small 7th-century Virgin and Child in the left side altar.
The roof and bell tower were destroyed by fire caused by a lightning strike in 1916. The residents quickly covered the charred framework with planks and rebuilt it in 1920–1921, with a larger dome than before.
Two bells were reinstalled, named Marie-Joséphine and Jeanne d’Arc.
