Gars am Kamp Castle was built around 1120-1130. The heterogeneously arranged complex of the hilltop castle stands on terraced land descending in three levels by the Kamp River.
On the highest level stands the main castle, enclosed by a ring wall. On the second, middle plateau, there are the southern gate tower and the castle chapel, a hall building from the 16th century to the west, and the surrounding fortifications from the 13th century. On the third, lowest level, connected by a castle path, the fortified outer bailey hosts the parish church of Thunau am Kamp on a southern terrace. A small coat of arms stone of the Rotthal family (dated 1709) is located above the portal to the north tower.
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.
