Piazza del Plebiscito is one of the oldest squares in the old town. It was called Piazza Nuova when it was first built in the late 15th century, and then Piazza Grande. It is where the boundaries of three old quarters – Porto, Capodimonte and San Pietro – meet. When the French conquered Italy in the late 18th century, the square was renamed Piazza Napoleone. Locals call it Piazza del Papa after the Baroque statue of Pope Clement XII, built by the Tuscan sculptor Agostino Cornacchini. Piazza del Plebiscito was the site of many important events in the city: the execution of Pietro Grifoli, a mayor in the Middle Ages, accused of treason, the founding of the headquarters of Giovine Italia.→
