A Palace without a king
When the Palace was constructed in 1600, Naples had no King. Since 1503, in fact, the city and the rest of the kingdom of which it was the splendid capital had lost its independence to the Spanish forces led by the condottiero Consalvo de Cordova, known as El Gran Capitan. For two centuries the Kingdom of Naples became an Iberian colony under the dominion of the ruling houses of Spain, first the Hapsburgs then the Bourbons. The viceregal government of Naples was given in turn, for periods of varying length, to trusted men of the court chosen from the Spanish aristocracy.
In 1600, the viceroy Fernando Ruiz de Castro, Count of Lemos, arranged the construction of the Royal Palace to mark the planned visit of King Philip III of Spain, a visit that subsequently never took place.
Around 1630, after lengthy works, the palace became the permanent residence of the viceroy.
