This is a story of research synthesis and Islamic archeology that we occurred on a geographical area North East Moroccan Taza, Debdou, Taourirt and the region. This is the first such research in Islamic archeology in this part of Morocco. Thus, this research fits into a larger perspective. It is the establishment of an archaeological map of the area, itself part of a vast archaeological program throughout Morocco. We evoked at first, the most famous monuments of the city of Taza, dating back to the Middle Ages namely religious architecture represented by the Grand Mosque and other monuments and defensive architecture through its ramparts and bastion. The second part of this article will focus on the medieval archaeological site of the city of Debdou and its components: the qasba and the mosque and the medieval town of Qasba Taourirt and the most important historical monuments of the city. We approach then the other historical monuments, little known which are very important on the architectural and heritage level, the medieval Qasba called "Merada" near the town of Guercif and Qasba Alouite called "Msoun", to 25 km east of the city of Taza on the national road linking Fez to Oujda. In this research special attention was given to the cartographic, graphic and photographic documentation.
