The establishment of the French protectorate is a decisive step in the history of Tunisia on all levels, political, social, economic and also urban. And we saw that we can address the efforts made by the colonial administration to establish an urban base consisting of facilities that serve the interests of the centenarians and European communities in general, and through which it seeks to encourage them to settle in Tunisian for the success of settlement colonization. The Kairouan region was a model for this trend, as the region witnessed agricultural development during the colonial period, which led to the creation of many small urban centers of a rural character, such as the Pichon district, which is currently the dependency of Haffouz in the province of Kairouan. In this article, we will focus on the conditions that helped centenarians invest in this region, and the steps that culminated in the concentration of a modest infrastructure in the midst of vast estates for urban residents, and although it did not rise to be a municipality, it was the center of Jlass. Our attention will also be focused on the archaeological side, as all those who have known a cultural presence dating back to the pre-Islamic period, the region witnessed some archaeological activities, including excavations and efforts to arrange some sites dating back to the Roman period on the list of historical sites.
