Walzin Castle is located over the river Lesse near Dinant. Construction began in the 13th century, and the 15th-century Renaissance horseshoe tower with four cannon ports still exists, even though the castle was burned down by the French army in 1554. There were several restorations later, the latest by Baron Fréderic Brugman between 1930 and 1932. Victor Hugo made a drawing of it in 1863.
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.
