The Dark Passage, also known as Skifa el Kahla, was once an only entrance to the city of Mahdia about a thousand years ago. Its long dark entrance was notriously frightening, especially to all new visitors and invaders who could be trapped inside its darkness by iron grills. I waited until I saw people emerging from The Dark Passage before I made the picture. Although it was blazingly bright outside, I am sure the women were glad to be coming out of its darkness.
