Essaouira has two principal skala (fortified bastions), with fabulous cannons: the medina skala and the port skala. Each was a strategic maritime defense point. Unlike the straight-edged Moorish constructions in other Moroccan cities, the ramparts in Essaouira are triangular, so the insider looking out has a broader field of vision than the enemy peering in. Orson Welles filmed scenes of his film Othello from the tower of the port skala, picking up a magnificent panorama of town, port, and bay all in one that can still be seen today. The entrance fee is well worth it to get the picture-postcard view of the medina through a round opening in the wall.
