Il disegno della città ideale: Cosmopolis

In 1548, under the Florentine lordship of the Medici, Charles V gave Cosimo I de Medici the task of defending the territories of Elba and the commercial traffic of the Tyrrhenian Sea. The Duke, who strongly believed in the potential of the island and wanted to transform it into the center of Florentine rule over the Tyrrhenian, decided to fortify the ancient city of Ferraia, the current Portoferraio.
