The 12th-century Romanesque cathedral, is off Corso Vittorio Emanuele II. The lower half is Romanesque; the upper part was rebuilt in exuberant baroque style after the earthquake in 1731. Most of the cathedral’s treasures were lost in the quake but you can see a Byzantine icon preserved in a chapel inside the church. Legend has it that, in the 11th century, shepherds discovered the icon lying in a pond over which burned three flames. These flames are now the symbol of the city.
