The Royal Palace of Caserta is a former royal residence in Caserta, southern Italy, constructed for the Bourbon kings of Naples. It is one of the largest palaces erected in Europe during the 18th century. In 1997, the palace was designated a UNESCO World Heritage Site; its nomination described it as "the swan song of the spectacular art of the Baroque, from which it adopted all the features needed to create the illusions of multidirectional space".
