Following the traditional layout of medinas, theGreat Mosque dominates the centre of the medina in Sfax. The souks, largely unaffected by tourism and frequented by locals, are dotted around the mosque. Situated slightly away from the medina, the residential districts are home to some fine houses, such as theDar Jallouli , which shows strong Andalusian influence. Thekasbah , now home to the Museum of Traditional Architecture, stands on the site of the old ribat. Take a look at the kasbah's magnificent ramparts before exploring the medina, one of the most authentic in Tunisia.
