Piacenza, city, Emilia-Romagna regione of northern Italy, on the south bank of the Po River just below the mouth of the Trebbia, southeast of Milan. It was founded as the Roman colony of Placentia in 218 bc. After being besieged unsuccessfully by the Carthaginian general Hasdrubal in 207 bc and sacked by the Gauls in 200, it was restored and reinforced. In 187 bc it became the terminus of the Via Aemilia, the great arterial road to Ariminum (Rimini), and was later the focus of other major Roman roads.
