In a very short time, the colonial city transformed rapidly. As the city has grown and native Tunisians gradually began to replace the extensive European population, conflict between the Arab city and the European city has gradually decreased with the arabization of the population.
Because of population pressure and the rate of migration to the capital, the city continued to grow, even with the creation of new districts in the suburbs. Old buildings have gradually been renovated and upgraded and new buildings have come to influence the urban landscape. At the same time, an active policy of industrialization is developing the municipal economy.
