Figuig is an oasis in extrem eastern Morocco, surrounded by the Algerian border. It is geographically isolated. Since the closure of the border in 1994, it is economically isolated. Moreover, a political isolation has long kept out of national development programs and actions fostering heritage. This isolation paradoxically allowed Figuig to preserve earthen architecture, a large palm grove and cultural traditions from a rich past of caravan crossroads. It can be likened to an "heritage bubble" We show in this paper how an oasis in a situation of "heritage bubble" manages to retain its cultural heritage, despite multiple interactions between actors to global logic.
