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:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
