The Maison des Traditions et du Patrimoine is located in the old town hall in the center of town.
The municipality of Istres has grouped together in the former town hall the associations that manage Istres' and the region's heritage. Each of these associations (Les Amis du Vieil Istres, l'Escolo dis Arnavaux, Saint Etienne Renaissance, le Comité des Bergers, la Chorale Provençale, etc.) has its own meeting room.
