The Citadel of Dinant (Citadelle de Dinant) was built in 1815 on a site which was originally fortified in 1051 when the region was ruled by the Prince-Bishopric of Liège. The citadel overlooks the city of Dinant and the strategic Meuse river which runs through the town. It is open to the public.
Together with Huy, Liège and Namur, the Citadel of Dinant forms part of the so-called Meuse Citadels.
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.
