The Palace of Caserta is a palace in Italy. It is just outside Naples. It was built by King Carlo VII of Naples. It was one of the largest buildings built in Italy in the 8th century. It was mainly used as a summer residence of the royal family of the Two Sicilies. In Italian it is known as the Reggia di Caserta. The palace has some 1,200 rooms, including two dozen state apartments, a large theatre modelled after the Teatro San Carlo of Naples. It is often compared to the Palace of Versailles and therefore called the "Italian Versailles".
