We got a "black and white" taxi from the Ramses Hilton to take us to the Citadel in Cairo. Ashrahim agreed to wait for us while we toured the Citadel for 1.5 hours. The Citadel is a very large walled medieval fortress that was built to defend the city for attacking crusaders. Inside the Citadel walls is the imposing Muhammad Ali mosque, which is huge and can bee seen from miles around. From the outside it seems that the mosque could have many, many levels of storeys, but when you go inside you realize that there is only one -- with a very very high domed ceiling, seems hundreds of feet high, I but I don't know for sure. As the Citadel is located ar the top of a hill, much of Cairo can been see from the edge of the Citadel walls. A group of Egyptian school girls asked to take a photo with us. We are not really sure why they wanted to, but apparently this is not uncommon. We then went down and met our cab driver.
