 A Roman sarcophagus with fragments of painted plaster was discovered in modern times.The excavations also unearthed a tympanum depicting the Lamb of God on a blue background and flanked by Saints John the Baptist and John the Evangelist; a Madonna and child between Saints Agatha and Susanna; plus five beautiful busts of other saints.Behind the chancel, separated by an iron grating, is located the splendid monastic choir, a large rectangular room.
