Zarafona Castle is a good sample of late medieval fortification architecture. It is in relatively good condition According to an inscription found on the west external wall, the castle was constructed in the period that the Despotate of Moreas was governed by Theodoros II Paleologos (1407-1448). Therefore it was a construction of the first half of the 15th century, part of the effort of the Byzantines to confront the Ottoman threat.
The castle has an almost trapezoid layout and covers an area of 745 square meters. There are 3 towers, two at the west wind and two at the east. The walls are divided in 5 straight parts of vertical walls.
The central tower is much higher than the other buildings and the walls. It has 3 levels. The ground-floor houses a cistern.
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.
