Tunisia
An obvious influence on Art Deco was North African architecture, with white exteriors and rounded corners. French colonial Africa built many buildings in the deco style and many still survive. Many were for official purposes but apartments in the deco style are also fairly common.These were often originally built for the colonial settlers, sometimes to encourage immigration.
