The royal apartments include the Alabardieri Hall, Guards' Hall, and Alessandro Hall, which is located directly at the center of the main façade: they were all built under the direction of Carlo Vanvitelli, the son of the original architect, and weren't completed until the 1800s. The best artists of the kingdom were called to fresco the rooms and decorate them with marbles and stuccoes.
The royal apartments include dozens of rooms, and were all decorated and furnished with the styles that were popular between the 1700s and 1800s. After the Royal Palace was modified and damaged when it was used as the seat of the Allied Command in World War II, it took several decades to restore it and reopen it to the public.
