In this photo taken Wednesday, May 15, 2013, the illuminated Sultan Al-Mansour Qalawun complex on El-Moez street, a complex that was consisting of a hospital, a school, a mausoleum and a mosque, in the historical Fatimid Cairo, Egypt. Cairo, the Arab world's most populated city, is often referred to as an open-air museum of Islamic antiquities and the city of 1,000 minarets. But its rich history and contributions to Islamic art has languished. (AP Photo/Nasser Nasser) less
