Schloss Baldern was first mentioned in historical documents in the 11th century. In the mid-12th century, it was owned by a noble family known as the Edelfreien von Baldern. In 1280, the castle came into the possession of Count Ludwig V. von Oettingen. In the 15th century, it was pledged by his descendants and later redeemed in 1507. The current baroque appearance as the residence of the Counts of Oettingen-Baldern was established between 1718 and 1737. The construction was overseen by Franz de Gabrieli, and after his death, by his brother Gabriel de Gabrieli.
After the extinction of the noble family Oettingen-Baldern in 1798, the estate passed to the House of Oettingen-Wallerstein. Major renovations took place in the 19th century, including the landscaping of the hilltop into a landscaped garden. The tower was erected in 1887 under the direction of August von Beyer. As early as 1896, Schloss Baldern was opened to the public.
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.
