History
According to medieval historian Bonaventura da Lama, Valenzano was founded by a Greek man, named Valentinian or Valentian, who arrived in Apulia in the 8th-9th century escaping an invasion of Saracens. Historically, the area was inhabited in prehistoric and early historic times (up to 4th century BC) by the Peucetii, of Illyrian origins, as testified by funerary findings.
