One of my city tours included the Cairo Citadel. I didn’t know much about it except that the last time I drove past it was during Eid (one of the religious holidays) and it was packed with people.
I learned that the citadel used to be the city center and was fortified/walled to keep out the Crusaders, who were trying to spread Christianity through a series of religious wars. The walled complex used to be much larger, but was split in two when a major highway was built in the middle of it.
The citadel is now just a site that includes several defunct museums and three mosques, the most prominent of which is the Mosque of Muhammad Ali. It was built by Muhammad Ali Pasha in 1848 and is not related to the American boxer who took the same name. Side note: Muhammad, Mohamed and Ahmed are very popular names here; parents name boys after the Prophet himself.
It cost about $6 (more or less depending on what the dollar is doing on a given day) to enter the whole site as a foreigner. For locals, the cost is very minimal and as a result, it’s a popular gathering place. No shoes in the courtyard or interior of the mosque, obviously, but I didn’t have to cover my head. I wore long pants and a t-shirt and had no problems. It was a worthwhile trip to see the most recognizable white alabaster mosque in the “City of a Thousand Minarets.”
Thanks Wikipedia for details about the mosque.
