Maglaj Fortress is a large castle mentioned for the first time on in 1408 in the charter of the Hungarian king Sigismund. Although it was made in 14th century to serve in the defence of the Bosnian kingdom, not until the time of the Ottoman rule did the Fortress get its final shape. Fortress Gradina was declared a national monument of Bosnia and Herzegovina in 2005.
The Fortress Gradina consists of 5 towers: Širbegova or Kapi tower, Dizdareva or Southern tower, Defender tower, The Captain's or North tower and the Clock Tower. The exact data that we posses about the construction of the Maglaj Fortress is only about the Clock tower, and all the information on the appearance, construction and dimensions of the other parts of the Fortress are currently unavailable.
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.
