On the Capitoline Hill, this landmark church was built for the Franciscans in the 13th century. According to legend, Augustus once ordered a temple erected on this spot, where a prophetic sibyl forecast the coming of Christ. In the interior there’s a coffered Renaissance ceiling and the tombstone of Giovanni Crivelli (1432) carved by the great Florentine Renaissance sculptor, Donatello. The church is also known for the Cappella Bufalini ★ (first chapel on the right), frescoed by Pinturicchio with scenes illustrating the life of St. Bernardino of Siena.

You have to climb a long flight of steep steps to reach the church, unless you’re already on neighboring Piazza del Campidoglio, in which case you can cross the piazza and climb the steps on the far side of the Musei Capitolini.
