If you are in Naples don't miss the opportunity to visit the incredible Royal Palace that was the seat of the monarchy in Naples and Southern Italy for three centuries, from 1600 to 1946 - beginning with the early Spanish and Austrian Viceroys, followed by the Bourbon Kings and ending with the Savoy royal family. The Royal Palace has housed the Museum of the State Apartments and the National Library since 1919 and has thus taken on a different cultural role in city life.
