The parish church (9th-10th century) was built before the age of one thousand.
The object of numerous restorations, the ancient church had a rectangular plan, with the canonical proportions of early Christian churches.
In 1513, Cardinal Adriano da Corneto had everything razed to the ground, with the exception of the chapels, and rebuilt. In 1893/96, it was subjected to new restoration work.
The interior of the church is striking for its size. On the vast central nave there are eight chapels connected by a nineteenth-century gallery.

Of particular interest are the baptistery, the frescoes (in particular the Madonna and Child by Simone Baschenis), the Via Crucis, the marble High Altar and three precious wooden statues from the 16th century, perhaps by the Maffeo Olivieri.
