Several reconstructions have left little to admire of the once-Romanesque Duomo. Inside is the Cappella del Santo Chiodo (Chapel of the Holy Nail), built in the 15th century to hold a nail allegedly from the cross upon which Christ was crucified. (Perhaps it inspired the locals to go into the nail-making business, which became another of the town's flourishing industries.)
