The Piazza del Plebiscito in Naples was for centuries a widening irregular, where festivities were held around the so-called party machines. Only from the beginning of the 17th century onwards it was gradually "regularized", partly because of the construction of the new Royal Palace, designed by Domenico Fontana. But it was only in the early nineteenth century, during the Napoleonic period, which completely changed the square face. By order of the French monarchs, it was entirely redesigned and rethought: were demolished too many religious buildings that limited space and prevented by inserting it in the surrounding urban context and in place of these palaces were built, State setting of the famous Doric hemicycle in lava stone and marble, commissioned by Joachim Murat and designed by Leopoldo Lafferty in the middle of what was supposed to be another civil building, dedicated to the glories of Napoleon. In the middle of the Colonnade stands out instead the Basilica of San Francesco di Paola, who is the dominant element and was built by Ferdinand I, as an ex voto for regaining the Kingdom after the Decade of French rule. Isolated on the square in front of the basilica, rise the equestrian statues of Charles III of Bourbon and Ferdinand I.
