Cairo is the capital of Egypt and, with a total population of Greater Cairo metropolitan area in excess of 16 million people, one of the largest cities in both Africa and the Middle East (the regions which it conveniently straddles). It is also the 19th largest city in the world, and among the world's most densely populated cities.

On the Nile river, Cairo is famous for its own history, preserved in the fabulous medieval Islamic city and Coptic sites in Old Cairo — with historic Cairo inscribed on the UNESCO World Heritage list. The Egyptian Museum in the city centre is a must see, with its countless Ancient Egyptian artefacts, as is shopping at the Khan al-Khalili bazaar. No trip to Cairo would be complete without a visit to the Giza Pyramids and to the nearby Saqqara Pyramid Complex, where visitors will see Egypt's first step pyramid built by the architect Imhotep for the third dynasty pharaoh Djoser.

Cairo is on the Nile, and has ancient origins in the vicinity of the Pharaonic city of Memphis. The city started to take its present form in 641 CE, when the Arab general Amr Ibn Al-Ase conquered Egypt for Islam and founded a new capital called Misr Al-Fustat, "the City of the Tents".
