The site has been one of the most important and strategic ports on the Mediterranean sea, yielding a rich Greco-Roman heritage. It was an independent Lombard principality, Principality of Salerno, in the early Middle Ages. During this time, the Schola Medica Salernitana, the first medical school in the world, was founded. In the 16th century, under the Sanseverino family, among the most powerful feudal lords in southern Italy, the city became a great centre of learning, culture and the arts, and the family hired several of the greatest intellectuals of the time.
