The Medina of Fez, located in northern Morocco between the Rif and the Middle Atlas Mountains, is a historical medina founded in the eighth century under the Idrissid dynasty. It does illustrate a remarkable continuity despite historical challenges by preserving its unique identity through 12 centuries. The history of its founding, broadly accepted but nuanced, deserves in-depth analysis to better understand its early development and transformation. Although recognized as founders, the Idrissid dynasty failed to leave detailed historical documents regarding the foundation of Fez. Historical narratives of the founding period are largely based on fourteenth-century texts, particularly the works of Ibn Abi Zaraa. However, the credibility of these sources has been questioned, especially by the research of Henri-Michel Lavoix, Georges Seraphin Colin, and Evariste Lévi-Provençal. These studies have criticized the traditional narrative attributing the founding to Idriss II, thereby underlining the complexity of Fez’s history. Our focus in this study is to investigate the identified inconsistencies as a starting point, we wish to delve into new research pathways that question the space created as a source of historical storytelling. To accomplish this, the study employs an extensive multidisciplinary methodology, which is centred on engaging in comparative analysis and thorough exploration of historical sources:
