Triumph of the Italian Baroque, the Palace is one of the most important works of the famous neapolitan architect Luigi Vanvitelli who, commissioned by Charles III of Bourbon, has created a work well-kept in the details and with four monumental courtyards. Not forgetting the beautiful park, today visited by thousands of tourists. Significant influences come from the famous Royal Palace of Versailles of the kings of France and from the Escorial Palace of Madrid, home of the King of Spain. With its five floors the monument reaches a height of 36 metres; the building is made of brick and the two lower floors are covered with slabs of travertine. It overlooks on the entire structure a large central dome. The interior is rich with stucco, bas-reliefs, frescoes, sculptures, inlaid floors; like those of the Astrea’s Hall, the Hall of Mars and of the Throne Room. The lobby and grand staircase of honor with the chapel are the spaces with most visual and theatrical impact: the staircase connects the lower and the upper vestibule, which leads to the royal apartments. While, the Palatine Chapel, designed by Vanvitelli, is very similar to the model of Versailles. The park, a typical example of Italian garden, is of exceptional beauty and is made up of fountains and waterfalls enjoying spectacular water features. In addition to the Royal Palace and its park, the UNESCO has also entered the Aqueduct, also built by the architect Luigi Vanvitelli, and the San Leucio Complex.
