During the occupation of Corsica by Pisa and Genoa over several centuries, a large number of stone bridges were built between the 13th and 18th centuries. The number of these bridges testifies to the economic reorganisation of the island during the Genoese domination. These structures were fundamental to progress, as roads and bridges became essential for the transport of the island's main products: wheat, wine, olive oil and chestnuts, which were the basis of the island's food and economy.
