The Cistercian convent moved to Nimbschen before 1291 from Grimma. The Cistercian nuns faced financial difficulties in the late Middle Ages, and reforms were attempted by the Wettin rulers and Pforta abbots. Despite extensive renovations in the early 16th century, the community faced challenges. The influence of the Reformation became evident, leading to the escape of nine nuns, including Katharina von Bora, Luther's future wife, in 1523. The last Abbess, Margaretha, died in 1536, leading to the dissolution of the convent in 1536. The estate continued under a steward until Kurfürst Johann Friedrich von Sachsen leased it in 1542.
After secularization, from 1550 to 1948, Nimbschen belonged to the Fürstenschule in Grimma, providing financial support for gifted students. The secularized estate was managed by the Grimma school office, overseeing the school's economic well-being.
Over time, the convent buildings deteriorated, and in 1810, they were repurposed for construction material. In 1901, a new estate was built using the remaining materials.
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.
