The stratigraphic analysis applied to the architectural space of the mosque of Sidi Ghanem of Mila, through the material imprints inscribed in the masonry, has allowed us to recognize the different constructive phases and to define seven stratigraphic units. The relative chronology resulting from the stratigraphy and the characterization of the building materials allowed us to locate the different historical phases of the different civilizations passing through this place (Roman, Byzantine, Muslim, Ottoman, and French) and to deduce a relative date of construction from historical accounts. The absolute chronological analysis by stimulated luminescence (OSL), allowed us to better specify the date of construction of the first part of this building, which is located in the interval 670–694 CE.
