The Citadel is built at the top of Cairo. You are supposed the be able to see the pyramids, but this is impossible due to the air quality. Some of the initial building materials were removed from the pyramids. The main attraction now is the 19th Century Mosque of Mohammed Ali (nothing to do with “the greatest”). In its courtyard is a clock given to the Egyptians by the French in exchange for the obelisk in the Place de la Concorde, but it arrived damaged and has never worked. We were surprised by how few tourists there were at the Citadel – for many Cairo is a staging post including only the pyramids.
