Cairo
Egypt's capital, the Arab world's largest city beside the Nile
No skyline in Africa carries more weight of memory than Cairo's, where minarets and apartment towers crowd the eastern bank of the Nile within sight of the pyramids of Giza. Egyptians call it Misr, the same word they use for the country itself, an elision that captures how thoroughly the capital stands in for the nation. Home to more than twenty million people across its sprawling metropolitan reach, it is the largest city in both Africa and the Arab world, a place where the rhythms of five millennia of civilization fold into the noise and ambition of a modern megacity.
Cairo sits at the apex of the Nile Delta, where the river fans out toward the Mediterranean after its long passage from the African interior. The historic core rises only a couple of dozen meters above the water, hemmed by the Mokattam limestone hills to the east, atop which the medieval Citadel of Saladin commands the view. The river splits around the green islands of Gezira and Roda before the city gives way to desert on both flanks. To the southwest, across the Giza plateau, the Great Pyramid still anchors the metropolitan edge, while a new administrative capital has been raised from bare desert farther east to drain population from the congested center.
The Fatimids founded Cairo proper in 969 as a walled royal city, but settlement on this stretch of the Nile reaches back to the ancient capital of Memphis and the Roman fortress of Babylon, whose Coptic churches still stand. Under the Mamluks and Ottomans the city accumulated one of the densest concentrations of medieval Islamic architecture anywhere, the mosques and madrasas of its old quarter now a UNESCO World Heritage Site. Today Cairo is the political and cultural engine of the Arabic-speaking world, the seat of Al-Azhar and the Egyptian film and publishing industries, its Tahrir Square seared into recent memory as the stage of the 2011 uprising.
