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.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
