Šomoška Castle is unique among the Slovak castles as it is built of unconventional hexagonal basalt pillars. It was probably built in the later half of the 13th century after the Tartar invasion. After suppression of the Rákoczis rebellion, the Emperor had pulled down several castles, but Šomoška was spared. However, it gradually decayed and the last tower burnt in 1826 when a lighting struck it. In 1972 extensive conservation and partial reconstruction saved the castle before its total destruction.

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.
