Dasburg Castle lies in the village of the same name, next to the German-Luxembourg border, in the Rhineland-Palatinate region in Germany.
Dasburg Castle was probably built during the 9th century by King Pippin. He donated the castle to the Abbey of Prüm who used it as a refuge. In the beginning of the 13th century it was still owned by the abbey but it was lent to the Counts of Vianden. These Counts used it to defend their castle at nearby Vianden. In 1414 the castle was transferred to the Counts of Nassau.
From 1580 until 1604 the castle was owned by King William of Spain. During the 17th and 18th century the castle was property of the Nassau of Orange family.
In 1813 the castle, which was in French hands at that moment, was sold at an auction by Marshal Nicolas-Charles Oudinot with the stipulation that it should be torn down. It has been a ruin ever since.
The castle is now used as a small village park and is freely accessible.
References: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.
