The first castle at Burgistein was built by Jordan I of Thun (later of Burgistein) in 1260. Jordan III of Burgistein fought on the losing side in the Battle of Laupen in 1339. In retaliation a Bernese army attacked and destroyed the castle in 1340. It was rebuilt in the following years.
In 1397 the Burgistein family died out and the castle was inherited by Werner Münzer. Over the following century it passed through numerous owners until 1484 when the Wattenwyl family acquired it. They owned the castle until 1714, when it passed to the Graffenried family. The 14th-century castle was rebuilt in the 15th and 16th centuries.

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.
