Originally in this area there was a small Roman era church dedicated to St. Peter. The construction of the new church began in the 14th century. It only ended in 1452 with the construction of the great apsidal tribune, when Stefano Manassei greatly contributed because of his wish to be buried in the church. Today, the funeral tomb is preserved in the right wall of the presbytery. The building was badly damaged by the earthquake of 1703 thus requiring a radical restoration. The interior was renovated in a Baroque style. Post-war restorations sought to recover medieval forms. When the 18th century stuccowork was demolished, numerous collections of frescoes from the 14th and 15th centuries came to light. The large gabled façade is adorned with a beautiful portal with columns surmounted by a triangular tympanum where a precious bas-relief depicting the blessing Christ is embedded. The interior with a single nave looks like a large bare and austere room, and it is completed by a large polygonal apse in Gothic style. Along the walls you can admire some collections of frescoes. The monumental bell tower is very elegant. It is characterized by a double order, the lower one with mullioned windows from the Middle Ages and the upper one with arcades built in the 18th century.
