Fodor's Expert Review Duomo

Severe yet mystical, the Cathedral of San Lorenzo is most famous for being the home of the wedding ring of the Virgin Mary, stolen by the Perugians in 1488 from the nearby town of Chiusi. The ring, kept high up in a red-curtained vault in the chapel immediately to the left of the entrance, is stored under lock and key—15 locks, to be precise—most of the year. It's shown to the public on July 30 (the day it was brought to Perugia) and the second-to-last Sunday in January (Mary's wedding anniversary). The cathedral itself dates from the Middle Ages, and has many additions from the 15th and 16th centuries.
