The National Opera House was constructed in 1863 by architect Ludwig Bohnstedt from St. Petersburg, for the then German-speaking City Theatre. It has been refurbished several times; 1882-1887 (following a fire in 1882), 1957–1958, 1991-1995 (following independence). A modern annex was added in 2001 with a 300-seat New Hall.
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.
