Palazzo Reale was one of the four residences of the King of Naples during the reign of the two Sicilian kingdoms (1730-1860) in the Bourbon Dynasty. It was built by architect Dominique Vontana in 1600, and later rebuilt many times. It became the palace of the Bourbon Dynasty after the 18th century. On the eight huge walls on the front of the palace, there are eight marble statues of the most important king in the city of Japan, which are filled with the spirit of Baroque architecture.
