There’s no other city in the world like Cairo. The inner city area has about 8 million people while the outskirts has about 16 million people, and they’re from all over this region. You’ve got every type of nationality, and many different religions, it’s a place of great ethnic diversity, and lots of great things to see.
On the shores of the river, on what is actually an island known as Gezira, you’ll find the Gezira Palace built by the Khedive Ismail in the mid 19th century.
