Dobczyce Castle was first mentioned in written sources in 1362, but had been fortified since 1311. In the time of Casimir III the Great, the walls were from 5 to 9 meters thick, and the castle was a fortified stronghold. In 1398, the castle was the abode of King Władysław II Jagiełło and his wife Jadwiga. In 1473, for several months, Prince Casimir stayed here after returning from an unsuccessful expedition.
The Lubomirski family, who ruled the castle from 1585, rebuilt the Gothic fortress into a Renaissance residence in the years 1593-1594. The clocktower, chapel and fountain were added. By 1620 the castle had 70 rooms and 3 towers. In the 1960s the site was extensively excavated.
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.
