The White Tower is a monument and museum on the waterfront of the city of Thessaloniki. The present tower replaced an old Byzantine fortification, known to have been mentioned around the 12th century, that the Ottoman Empire reconstructed to fortify the city's harbour sometime after Sultan Murad II captured Thessaloniki in 1430. The tower became a notorious prison and scene of mass executions during the period of Ottoman rule.
The White Tower was substantially remodeled and its exterior was whitewashed after Greece gained control of the city in 1912. It has been adopted as the symbol of the city.
The White Tower houses an exhibition dedicated to the city of Thessaloniki and its history throughout various periods, organized by the city's Museum of Byzantine Culture.
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.
