The Haichenbach hilltop castle is located at an altitude of 450 meters above sea level on the ridge that forms the so-called Schlögener Schlinge on the Danube.
The first documented mention of Haichenbach dates back to 1160. At that time, Otto and Wernher de Eichenbach are mentioned as representatives of the ministerial noble family that derived its name from the castle. In 1273, the castle must have burned down for unknown reasons, as Rueger von Haichenbach documented in Schlägl in 1274 that he allowed the use of his forests in exchange for accommodation in the monastery hospital, during the time Haichenbach was being rebuilt.
After 1529 Haichenbach Castle was abandoned. Since 1984, restoration measures have been undertaken by the Working Committee for Homeland Care Hofkirchen; the castle ruins can now be safely visited.
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.
