Built around 1532, also with the contribution and work of the citizens, it was consecrated in 1538. The building was seriously damaged as a result of disagreements and repeated raids by Waldensian religious movements. The high altar, built by a craftsman from Thures at the beginning of the 18th century, was later repainted by a master gilder from Pragelato using no less than six thousand sheets of gold. It features a panel of carved wooden columns framing the image of the baptism of Christ.  On the baptismal font (1540), in green marble from Foresto, is carved the coat of arms of the Dauphins of France. The wrought iron lock (1534) on the side door is of exquisite workmanship. The bell tower, in pseudo-Romanesque style, has a square plan and is divided into five storeys. Above it rises a high central spire with an octagonal section embellished with four small triangular spires.
