Napoli is a ballet in three acts. The story of the ballet and the dances are the work of August Bournonville. The music was written by E. Helsted, Gade, and Paulli. "Napoli" was first danced by the Royal Danish Ballet in Copenhagen on 29 March 1842. "Napoli" has not changed over the years. It is danced in Copenhagen today exactly as it was danced in 1842. It is said to be Bournonville's greatest ballet.
