The original church is cited as early as the 11th century and was located on an ancient Gallo-Roman site in Trossy. It was first mentioned between 1078 to 1202. The new Sardinian neo-classical style church, designed by the Annecy architect Eugène Dénarié, was built between 1847 and 1848 with a dome on a Latin cross floor plan.

The entrance is through a door on the north side of the church. Free admission all year round.
