Since I don't have classes to teach on Monday, I was able to go with
Nancy and Trish on a tour of the Citadel. This structure appears as a
fortress with thick walls on a high point overlooking the center of Cairo,
and dates from Medieval Cairo. The inside was a small protected city, and
most of the interior buildings have been rebuilt by various rulers over the
centuries. There are several ornate mosques that are still actively used,
and we could see the different styles of the times in which they were built.
