Bočac Fortress is located on the left bank of the Vrbas River, on the half of motorway E661, between Banja Luka and Jajce. It was built in the early 15th century on a rock, in order to defend the crossing over the Vrbas River. The Fortress was mentioned for the first time in a charter from 1448. From 1463 to 1527, when it fell under the Ottoman rule, the city used to be the fortification of the Banovina of Jajce. In the early eighteenth century, Bočac was mentioned as a settlement with a few cannons. It was abandoned before 1833. During the Ottoman occupation it was subsequently fortified and maintained and the fortified walls and towers that surround the large garden of the town are relatively well preserved today.
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.
