Attached like a sinister balcony to the bell tower of Piacenza's 12th-century Duomo is a gabbia (iron cage), where miscreants were incarcerated naked and subjected to the scorn of the crowd in the marketplace below. Inside the cathedral, less evocative but equally impressive medieval stonework decorates the pillars and the crypt, and there are extravagant frescoes in the dome of the cupola begun by Morazzone (1573–1626). Guercino (1591–1666) completed them upon
Morazzone's death. The Duomo can be reached by following Via XX Settembre from Piazza dei Cavalli.
