The first hill fort overlooking the valley of Wolfach was built by Count Rapoto I von Ortenburg around 1120. Due to the power of Ortenburg house there were many conflicts with neihgbor states in the late 12th century and early 13th century. The castle was destroyed in one of these wars in 1192 and subsequently rebuilt. The medieval castle was sacked and almost completely destroyed in Landshut War of Succession in 1504.
The current Ortenburg castle was built in its current form as a renaissance castle in 1562. The interior furnishing of the halls had been first completed in 1800. Therefore, the castle holds interior decoration and art dating back over the course of two centuries. The precious coffered ceiling of the castle chapel is particularly worth noting. The ceiling, which had been made with five different types of wood, is among the most significant renaissance wood ceilings in Germany. Further art treasures included the knights’ hall and the renaissance inner courtyard. Today, the castle is home to the Ortenburg Castle Museum.
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.
