The Haichenbach hilltop castle is located at an altitude of 450 meters above sea level on the ridge that forms the so-called Schlögener Schlinge on the Danube.
The first documented mention of Haichenbach dates back to 1160. At that time, Otto and Wernher de Eichenbach are mentioned as representatives of the ministerial noble family that derived its name from the castle. In 1273, the castle must have burned down for unknown reasons, as Rueger von Haichenbach documented in Schlägl in 1274 that he allowed the use of his forests in exchange for accommodation in the monastery hospital, during the time Haichenbach was being rebuilt.
After 1529 Haichenbach Castle was abandoned. Since 1984, restoration measures have been undertaken by the Working Committee for Homeland Care Hofkirchen; the castle ruins can now be safely visited.
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.
