In 1383, the Davensberg branch of the noble lords of Büren acquired a newly constructed castle from Archbishop Friedrich of Cologne as a fief. It was intended as an outpost in the Almetal and was to be jointly owned by the Davensberg and Cologne Archbishop.
In 1394, the Davensbergs pawned the castle to Johann von Scharfenberg, a branch of the Padberg family. Concurrently, the noble lords of Büren pawned their half of the castle and town of Alme to Hermann von Padberg. The redemption of the Ringelstein castle took place in 1399 by Berthold von Büren.
While often suggested to defend against the Padbergs, there is no evidence linking the pawning and redemption of Ringelstein and Alme castles for this purpose.
In 1458, the castle was granted as a fief to the Landgrave of Hesse. During the Thirty Years' War, Ringelstein became a venue for witch trials, with a judicial site and torture facilities. In 1631, 55 people were convicted and executed as witches within 30 days. After 1802, Ringelstein declined in significance and fell into ruin.
The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
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.
