The ancient "Venusia" is located in the Vulture area, near the border with Puglia. The name has clear Roman origins and for the local traditions it derives from the name of the goddess Venus. In 291 it became a Roman colony in 65 B.C. was the birthplace of the Roman poet Horace. After the fall of the Roman Empire and the continuing attacks of Heruli and Ostrogoths, the town fell under the Lombard rule, becoming a Gastaldato (dukedom). It then submitted the domain of the Byzantines and the Normans, that settled in the district of Drogone of Altavilla, proclaiming it fief. Raided and sacked by Ruggero II of Sicily, under the rule of the Swabians, a castle was built. In 1232 it became the birthplace of the future Swabian Emperor Manfredi , son of Frederick II and Bianca Lancia. In the XV century the Duke Pirro del Balzo had built the Cathedral of St. Andrew and the Castle (demolishing the old church of San Felice).
