In the first chapel of the right, there are frescoes by Fra Emanuele da Como and monument to Cardinal Michelangelo Ricci by Domenico Guidi.
Notable also is a copy of an alleged portrait of St. Francis by the friar Margaritone d'Arezzo: if confirmed, it would be the first true portrait in the history of Italian arts (the original is in the Pinacoteca Vaticana).
