Kamičak was first mentioned in 1345 in a document issued by the Croato-Hungarian king Ludovik I of Angevin to confirm the property of the castle to Ivan II Nelipić, whose family possessed it at least from the 11th century. According to oral tradition, it is assumed that Petar Svačić (Snačić), the last king of the independent Kingdom of Croatia, killed in the battle of Gvozd Mountain in 1097, was born in Kamičak, since the Nelipić family descended from the Svačić tribe. The last male member of the Nelipić family was Ivaniš (†1434), who gave the castle to his son-in-law Ivan VI Anž Frankopan. The king Sigismund of Luxemburg however did not recognize it and gave the castle to Talovac noble family.
In 1445 Kamičak was given to Grgur/Gregory Utješinović, who donated the island of Visovac to the members of Franciscan Province of Bosna Srebrena. His son, the influential Cardinal Juraj/George Utješinović was born in the castle in 1482.
A couple of years later, the castle belonged to the Halapić brothers, who were present at the election of Croato-Hungarian king Vladislaus II Jagelović in 1490. There are some other people who originate from Kamičak area, for instance Marko Mišljenović, Ban (Viceroy) of Croatia, who ruled 1506–1507.
After conquering Kingdom of Bosnia in 1463, the Ottoman forces increased pressure on Croatian borders all the time, which lead to fall of Kamičak in 1522/1523. The castle was ruined and, having had no importance for the Turks, completely abandoned never to be rebuilt.
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.
