The ruins of the Revište Castle near Hliník nad Hronom stand on top of steep rock about 100 m above the floodplain of the river Hron. There is a wonderful meadow below the castle used by canoeist as a camping site.
The castle was built in the 13th century as part of protection to central Slovakian mining towns and the trade route running along the Hron. Renaissance fortifications were added to the older Gothic part of the Castle. Mercenaries of the rebellious magnate Imrich Thököly conquered the castle and converted it in ruins in 1678. Only some Castle walls survive.
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.
