Prayer hall of the Sultan Ahmed Mosque (Sultan Ahmet Camii), or Blue Mosque, 1609-16, by Mehmet Aga, Istanbul, Marmara, Turkey. Built near the Hagia Sophia, the Blue Mosque combines Byzantine elements with Islamic architecture in the Classical Ottoman style. The blue tiles of the interior inspired its popular name. The historical areas of the city were declared a UNESCO World Heritage Site in 1985. Picture by Manuel Cohen.
