The Prümerburg is a ruined hill castle on a roughly 30-metre-high lias-sandstone rock on the upper edge of the valley of the Prüm in the municipality of Prümzurlay in the county of Bitburg-Prüm in the German state of Rhineland-Palatinate.
The Prümerburg, a fief of the counts and dukes of Luxembourg, is first recorded in 1337, but was probably built in the 12th century. In the immediate vicinity there was an earlier prehistorical hillfort (Wallburgen). The castle's features include the remains of a pentagonal bergfried. The Prümerburg is believed to have burned down in 1658.
In 1337, Walter of Meysenburg is the first recorded vassal. In 1351, Godfrey of Meysenburg and his wife, Catharina of Homburg, were the enfeofees, later Prümzurlay, like Clerf, went to the lords of Brandenburg (a side line of the counts of Vianden). Subsequently there is evidence that the von Vinstingen and von Haracourt families (both by marriage) were vassals. A line of the von der Heyden family bought the Lordship of Prümerburg in the Early Modern Period, along with Niederweis and Stolzemburg.
To the northwest in the valley, the castle chapel, the Late Gothic former Chapel of St. Nicholas, has survived.
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.
