Napoleon III began his regime by launching a series of enormous public works projects in Paris, hiring tens of thousands of workers to improve the sanitation, water supply and traffic circulation of the city. To direct this task, he named a new prefect of the Seine department, Georges-Eugène Haussmann, and gave him extraordinary powers to rebuild the center of the city. He installed a large map of Paris in a central position in his office, and he and Haussmann planned the new Paris.
