The small Tuscan town of Monterchi has repeatedly refused to loan a rare fresco by the Renaissance master Piero della Francesca to Rome’s Capitoline Museums. Ownership of the work, which was painted on a church wall in the 1450s, has been murky, prompting the mayor of Monterchi to fear that if the works leaves the town, it might not return. The fresco attracts approximately 30,000 visitors to Monterchi every year.
