The construction of Rietburg castle is dated to the period 1200 to 1204 and ascribed to the lords of Riet. These noblemen were initially vassals of the North Alsatian Benedictine abbey of Weißenburg, later they became ministeriales and feudatories of the then German Hohenstaufen lords.
In 1470, during the Weißenburg Feud between Prince-Elector Frederick the Victorious of the Palatinate and his cousin, Duke Louis the Black of Palatinate-Zweibrücken, the Rietburg was shelled by Leiningen troops and badly damaged, but remained inhabitable. The castle survived the Palatine Peasants' War of 1525 unscathed, but was finally destroyed during the Thirty Years' War (1618–48) and never rebuilt.
Since 1954, a chair lift, known as the Rietburgbahn has run from the Rhine Plain up to a terrace on the eastern side of the Rietburg. The return journey offers good views over the plain. The bottom station is accessible on foot or by car and is located near the schloss of Villa Ludwigshöhe, a stately residence built from 1846 to 1852 by order of Louis I of Bavaria.

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.
