===Piazza del Duomo===The large Piazza del Duomo, dominated by the cathedral, is lined with other medieval buildings, such as the "Palazzo del Comune" and the "Palazzo del Podestà": it is the setting (in July) of the "Giostra dell'Orso" ("Bear Joust"), when the best horsemen of the d\city's traditional quarters tilt with lances at a target held up by a dummy shaped like a bear.
