There are some fine examples of colonial architecture in the Ville Nouvelle, ranging from the exuberant to the bizarre. Cathedral of St Vincent de Paul sits comfortably in the bizarre camp. This custard-coloured 1883 cathedral melds Gothic, Byzantine and Moorish elements. There are regular masses in French and Italian and it's open variable hours.
The statue opposite the cathedral is of Ibn Khaldun, the great Tunis-born Islamic teacher and philosopher - many of his ideas, such as the cyclical nature of history, were way ahead of his time.
