Norderburg is a moated castle that was established in the 14th century. It was destroyed in 1514 during the Saxonian rebellion and rebuilt in 1534 by Hicko Kankena.
The castle's architecture is quite impressive with a beautiful facade, flanked by two lion statues at the entrance, an ornately designed Knight's Hall, and a spectacular great hall that features baroque paintings. The castle changed many owners and was also used as a private school, and later as a college. Since 1951, it is home to a middle school.
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.
