Gottlieben village is first mentioned around the end of the 10th Century as Gotiliubon. It was originally part of the land owned by the Bishop of Constance. In 1251, Eberhard von Waldburg built a castle that served as the residence of the Bishops. After the Swabian War in 1499 the episcopal chief constable managed the village and the local low court from the castle until 1798. The court included Engwilen, Siegershausen and Tägerwilen as well as Gottlieben and made up the Bishop's bailiwick of Gottlieben. In 1808 the castle became private property. In 1837 it was renovated in a neo-gothic style.
References: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.
