Built in late antiquity, it was rebuilt in the 16th century. It houses precious and beautiful works of art, which bear the signature of great artists such as Bernini as well as a crypt that reveals a building from the Roman era, which can be visited. The building dates back to the first century, in which a monastery was established from the 5th century, of which fragments of frescoes from the 7th-9th century remain. An ancient tradition allocates the house of St. Luke, the presence of St. Peter and the prison of St. Paul to it. It houses the tombs of Joseph Napoleon Bonaparte and Zenaide Bonaparte.
