At the end of the spring of 1943, the German forces were finally defeated in Northern Tunisia and had to leave the country. This allowed the French protectorate to take power and in the years that followed, thanks to massive American economic aid, undertake a very important project of architectural construction and reconstruction. All of Tunisia was involved but the four main cities (Tunis, Bizerte, Sousse and Sfax), whose populations were expanding, saw entire parts of themselves reconstructed. Today, a unique experience of modernity still remains in the tissue of all these cities, but with big issues of conservation.
