The Castello di Naro was built on top of a hill in the 14th century by the Chiaramonte family. The complex includes walls with battlements, a square tower built by Frederick II of Aragon and the imposing 'mass of the male'. On the east side there are two mullioned Gothic windows that illuminate the great 'Hall of the Prince', which is located on the first floor of the tower. The portal is flanked by two rectangular bastions. The massive outer walls are interspersed with two cylindrical towers and two square towers.
Inside the walls there is a large courtyard, which housed the accommodation of the garrison, the chapel and the stables, and in the case of attack offered refuge to local farmers.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
