Anagni was the medieval papal capital — four popes were born here. The Cathedral Crypt is covered in 13th-century frescoes so stunning they call it "the Sistine Chapel of the Middle Ages." It predates Michelangelo by 200 years. €7 entry, 1 hour from Rome by COTRAL bus, and you might be the only tourist there.
