Introduction to the Baron's Former Residence: The Baron's Former Residence is the former residence of Baron Rodolphe d'Erlanger (1872-1932), the founder of the town. He was a French ethnomusicologist, Arab music historian and painter. The former residence of the baron is one of the most artistically valuable places to visit in the town. Now the former residence has been nationalized by Tunisia, and the red star and crescent flag flutters in the wind.
