The paper museum of Amalfi, is a former paper mill converted into a museum in 1969. The museum, located in the valley of the Mills, houses the machinery and equipment, properly restored and fully functional, used in the old paper mill to make paper by hand. Among the first cities where the existence of paper was discovered in the 12th and 13th centuries, there are the territories of the Maritime Republics: Amalfi, Pisa, Genoa and Venice which had warehouses, both in Syria and on the coast of Palestine, where the major centres for paper production were located.These Republics, moreover, had intense commercial relations with the East and could therefore have learned the art of paper making without difficulty, or it is not to be excluded that on board the "galleys", which in medieval times went back and forth between the Italian coasts and the Holy Land to transport crusaders and merchandise, "Magistri in arte cartarum" were embarked and that we introduced this art.
