The earliest sources of Gagi Castle dates from the 11th century. The Armenian historian Vardan (13th century) reported that it was built by King Gagic I (990-1020). The ruins of the castle however date from the older ages and probably Gagik I just rebuilt them.
The castle controlled the route leading to Tbilisi from the south. During the 15th century it also got known as Aghjakala, meaning 'White Castle', due to the color of its walls.
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.
