Cattedrale di Santa Maria Assunta e Santa Giustina
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. If you're feeling strong, you can climb the spiral staircase to the cupola for a closer view. Nearby at Via Prevostura 7, Kronos Museum displays the cathedral's collection of religious artworks, reliquaries, textiles and medieval manuscripts. Take Bus No. 4/17 or walk 20 minutes to the Basilica di Santa Maria di Campagna for more captivating cupola frescos by Pordenone (combined cupola ticket €15), plus panoramic city views.
