Like most of the castles in the Rhineland-Palatinate, Landeck Castle was built in approximately 1200. It served probably the function of protecting the nearby Klingenmünster monastery. The first documental reference to Landeck Castle was made in 1237.
In the period around 1500 there were castle administrators from the Kurpfalz, the bishop of Speyer and the counts of Zweibrücken. At the end of the 15th century extensive work was done at Landeck Castle. During the Peasants’ War in 1525 it was damaged, but obviously quickly repaired.
In 1570 there was again a change in ownership. After the dying out of the Zweibrücken-Bitch lineage their share of the castle went to the Kurpfalz. It was not until 1709 that the Electors succeded in owning the entire property of Landeck Castle, when the Speyer bishopric gave up the remaining quarter by exchange. The Kurpfalz remained the only owner until the French Revolution. In the 1960’s the castle was extensively restored.
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.
