Just behind the Pantheon hides the church of Santa Maria Sopra Minerva, a gem in its own right. The only Gothic church in Rome's center, it's a breath of fresh air from over-the-top Baroque opulence. Plus, it has gorgeous frescoes by Filippo Lippi (an early Renaissance master), the body of Italy's patron saint Catherine of Siena, the tomb of painter Fra Angelico, and a statue done, at least partly, by Michelangelo himself.
