Rabenstein Castle is the smallest medieval castle in Saxony. It is located in the Chemnitz suburb of Rabenstein and belongs to the Chemnitz Castle Hill Museum.
The hill castle Rabenstein was first mentioned in 1336 in a document from Louis IV, Holy Roman Emperor in which he promised it as a fief to his son-in-law Frederick II, Margrave of Meissen, in case the line of Waldenburg were to die out without male heirs.
At this time the castle was larger than the current. The castle walls consisted of a 180 m long wall, which enclosed an area of two hectares.

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.
