Cecilienhof Palace was built from 1914 to 1917. Emperor Wilhelm II ordered the establishment of a fund for constructing this new palace at Potsdam for his oldest son, Crown Prince Wilhelm (William) and his wife, Duchess Cecilie of Mecklenburg-Schwerin on 19 December 1912. Cecilienhof was the last palace built by the House of Hohenzollern that ruled the Kingdom of Prussia and the German Empire until the end of World War I. It is famous for having been the location of the Potsdam Conference in 1945, in which the leaders of the Soviet Union, the United Kingdom and the United States took important decisions affecting the shape of post World War II Europe and Asia. Cecilienhof has been part of the Palaces and Parks of Potsdam and Berlin UNESCO World Heritage Site since 1990.
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.
