Hauteroche ('High Rock') is a ruined 14th-century castle, destroyed after a siege in 1554, in the village of Dourbes in the municipality of Viroinval, province of Namur. It is situated on a ca. 50 meters high, rocky promontory, looking out over the valley of the Viroin river. The isolated site of the castle is separated from the plateau by a large, hand cut ditch. It has a square keep with 2.5 meter thick walls and it would originally have been at least 13 meters high.
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.
