Prudnik Castle was located in the defensive bend of the Prudnik river. It was built in 1255. It was founded a Czech knight Wok of Rosenberg.
The castle was destroyed in 1428 by the Hussites. After the end of the first Silesian War, Frederick the Great rebuilt the castle.
A fire on 27 August 1806 burnt the entire castle except of one tower called 'Wok's Tower', which is now the only remnant of the castle.

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.
