Dating from the 12th century, it is a fine example of the Alpine Romanesque style. The single nave is composed of three bays which open onto a quire flat chevet (like Notre Dame du Bourg in Digne for example). Before the quire, two chapels form a false transept. The western façade is decorated with a large rosette window above the portal. The second portal, on the south façade, is in the Gothic style of the 13th or 14th century.
The Alpine-style bell tower was built after the Wars of Religion.
