Very little is known of the Kantara castle's early days. It is thought to have been built by the Byzantines, probably after the last of the Arab raids in the late 10th century. However there are no remains or records dating from that time. Its first mention was in 1191, during Richard the Lionheart's Crusade to the Holy land. It was at Kantara that the self-styled king, Isaac Commenos, sheltered before surrendering to the English King.
In the 13th century, the castle was remodelled by the Lusignans, and during the next few hundred years, the castle often served as a shelter for defeated barons and kings. When the Genoese conquered Famagusta and Nicosia in 1373, Kantara remained undefeated in the hands of the King. It was here too, that Prince John, the king's brother, fled, disguised as a cook, after his escape from the Genoese. The story goes that the prince, having been captured in Famagusta with the rest of the Royal Family, was imprisoned in irons. With the aid of his faithful servant and cook, he escaped, dressed as the cook's scullion, with an old cooking pot over his head, and carrying a frying pan which he was supposedly taking to be re-tinned. After the peace treaty with the Genoese, Kantara was further re-fortified. Most of the castle that we see today dates from around this time.
When the Venetians took over the island in 1489, the castle continued as an important garrison for the defence of the area. However, the art of warfare was changing, and the Venetians strengthened the fortifications at Kyrenia, Famagusta and Nicosia. The castle was abandoned in 1525, though there are records showing the castle as still fortified in 1529. However records show the castle in ruins by 1562.
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.
