The ruin of Madenburg Castle is one of the biggest and oldest castle complexes in Rhineland-Palatinate. The castle was built on a cliff on the outskirts of the Palatinate Forest looking towards the Rhine rift valley.
In 1076 the Madenburg castle appears for the first time in a medieval document. Not a lot is known about the early owners of the castle, the counts of Madenburg. At a certain period it belonged to the Empire and to the Hochstift of Speyer. In 1470 Count Palatine Friedrich I. and his troops conquered Madenburg. In 1525, during the Peasants’ War, the castle was seriously damaged for the first time, but later rebuilt and renovated several times. In around 1689 French troops finally destroyed Madenburg.
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.
