Pope Francis looks at frescoes in the Cathedral Santa Maria del Fiore (Cathedral of Saint Mary of the Flowers) during his pastoral visit in Florence on November 10, 2015. Pope Francis delivered a major speech on the theme of work in the symbolic location of Prato, a small town near Florence that has become synonymous with Chinese immigration to Italy. The town became a symbol for both uncontrolled immigration and unchecked labour exploitation in December 2013, when seven Chinese workers burned to death in a fire in an unregulated workshop where they slept after 16-hour shifts.
