This is a 17th century church designed by Vittozzi which was built in the place where, in 1453, a miracle occurred. The church was built for the people after a vote taken during the plague in 1598. Inside, the place where the miracle happened is visible; the area is, however, enclosed and there is no access to it. There is a painting by Caravoglia illustrating the episode next to the site. The right altar was made by Juvarra, while the pulpit is by Perucca. On the walls, which are painted by Meyer, are frescoes of Vacca and and of S. Guiseppe in transit by Donnini.
