The village was the site of an ancient Goth castle, built in the 6th century, conquered by the Lombards and after by the Normans. During the Middle Ages, it was purchased by the noble houses of Sanseverino, Carafa and Pasca. The site was resettled in 1669, when a fire damaged Magliano and the survivors built a new village there, naming it Magliano Nuovo ("New Magliano"). When, some years later, the original site was rebuilt, it took the name of Magliano Vetere ("Old Magliano").[2]
