As well as seeing the pyramids and other ancient Egyptian sites, while we were in Egypt we also enjoyed visiting some more recent (but still historic) buildings.
One such was the mosque and madrasa of Sultan Hassan, dating back to the Mamluk period. I particularly loved the carved calligraphy, and the black-white-and-red patterns of the door frames and floor tiles. The open air, courtyard structure was also new to me, and not something that would really work in a rainy country like England! In Egypt, though, it makes a lot of sense.
