The first record of Kirumpää Castle (in German Kirrumpäh) dates back to the year 1322. It was one of the residences of Bishopric of Dorpat. The castle was destroyed in a Swedish-Russian war in 1658. Much of the ruins were used for construction in Võru town in XVIII-XIX century. Today, there is little left of the former castle. The ruins are located on a small scenic hill.

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.
