Hilgartsberg Castle lies on a mountain on the left bank of the Donau River. It was first mentioned in 1112. It was a fief of the Bishop of Bamberg and cared for by the Counts of Sulzbach. When the counts died out in 1188 the castle fell to a couple of sons of Frederick I, Holy Roman Emperor. They lent it out to Walchunus von Kamm.
In 1326 the castle came into the hands of the House of Eck. When Peter Ecker von Eck fell out of favor with Duke Albrecht I of Bavaria, the castle was besieged and conquered by the Duke in 1357. Albrecht then strengthened the castle and installed a castellan. Later it was lent out to several nobles. In 1617 it was used by the Fugger family, who considerably enlarged the castle after a big fire had damaged it in 1626.
In 1704, during the War of the Spanish Succession, Hilgartsberg Castle was occupied by Austrian troops. In 1742, during the War of the Austrian Succession, the Austrian troops returned and with help of Hungarian troops conquered and burned down the castle. After that it was a ruin and was never rebuilt.
Later the ruins were owned by a local brewer and the Bavarian State. And in the 1970s part of it served as the village school. At present Hilgartsberg Castle can freely be visited. It is used as a venue for cultural events.

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.
