Cairo is the capital of Egypt, and with a total population in excess of 16 million people, one of the largest cities in both Africa and the Middle East (which regions it conveniently straddles) - it is also the 13th largest city in the world. Situated on the River Nile, Cairo is famous for its own history - preserved in the fabulous medieval Islamic city and in Old Cairo - and for the ancient, Pharaonic history of the country it represents. No trip to Cairo would be complete, for example, without a visit to the Giza Pyramids, to nearby Saqqara, or to the Egyptian Museum in the center of town. Though firmly attached to the past, Cairo is also home to a vibrant modern society.
