Medina walls and gates by Willettsworld
The walls of the Medina have been heavily restored. The entire eastern wall no longer survives but those in the north, west and south are still quite impressive. Some interesting gates still survive such as Bab El Gharbi on the western wall and Bab Briqcha in the southern wall.
