The ruins of Ramstein Castle stand on a 182-metre-high, Bunter sandstone rock on the edge of the Meulenwald forest in the lower, steep-sided Kyll valley near Kordel.
The hill castle was built in the early 14th century by the Archbishop of Trier, Diether of Nassau as the successor to a fortified manor farm. From then on, it was a fief castle of the Electorate of Trier which was enfeoffed (subleased) to electoral subjects and cathedral deans. During the War of the Palatine Succession, the castle was occupied by French troops and largely blown up in 1689. The great damage was not repaired. However, tall sections of curtain walls, elements of corner towers and almost of all the exterior and the stone staircases of its medieval tower house stand.
Three larger-footprint modern buildings including a hotel-restaurant are on the southern part of the east-facing promontory. The hotel's outdoor terrace overlooks the lightly or densely wooded valley, depending on direction views. Fields have likely long stood next to the near-bend of the river enabling a clear view to the impassably sheer hillside (on horseback) on the opposite bank and intervening north–south route.
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.
