Church of San Giovanni in Monte

This is a 15th-century Roman Catholic temple, built on the ruins of a church from the fifth century known as Monte Oliveto, supposedly founded by Saint Petronius in 433. There's a lot of art here. The most important include: a Romanesque altar with octagonal columns and a cross from the 11th century, a sculpture of Christ on a cross from the 16th century and a crucifix by Jacopino da Bologna from 1361.
