Piacenza is a city in the Emilia-Romagna region of northern Italy. It is the capital of the province of Piacenza. Piazza Cavalli is the main square of the town. It is named ("Cavalli" means "horses") for the two bronze equestrian monuments of Alessandro Farnese (Duke of Parma and Piacenza from 1586, nephew and valiant general of Philip II of Spain) and his son Ranuccio, who succeeded him to the dukedom. The statues are masterpieces of Francesco Mochi, a Mannerist sculptor.
