The purpose of this article are to trace up the history of urban design in Florence of Renaissance era, to see how this urban design was introduced to Paris, and to depict the beginning of urban design in Paris. An axis, which connected SS. Annunziata-Santa Maria del Fore-Palazzo Vecchio-Palazzo Uffici, was also established there. Marie de Medicis, a grand daughter of Casimo 1, made the Palais du Luxembourg and the Cours de la Reine introducing those Italian designs to Paris. Colbert, Le-Notre and the Commisiion des Artistes were the successors of her design. They made the axis and urban designs of Avenue des Champs-Eysees and Avenue de Observatoire, making use of Marie's heritages.
