Bab el-Kasbah.
Bab el-Gharbi, the only entrance of the eastern half of the medina.
The medina has only got 6 entrances, each one different from the other. Looking at the picture, the difference between the main entrance of Bab Diwan and the modest Bab el-Gharbi is striking. Bab Diwan is the nicest of all the entrances, with 3 gates (lowest photo). The left gate is the oldest surviving and complete part of the walls, dating back to 1306.
