Löwenburg castle was built around 1200 by the Counts of Sayn. Together with the Castle of Blankenberg high above the valley of river Sieg it secured their territory. In the second half of the 13th century the old keep was torn down. Only then the castle whose ruins we see today was built. In the late Middle Ages the Löwenburg went through an eventful history until it fell to the Counts of Berg in 1484. It was destroyed in the Thirty Years War.

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.
