The Po Valley, Po Plain, Plain of the Po, or Padan Plain ( or Val Padana) is a major geographical feature of Italy. It extends approximately in an east-west direction, with an area of including its Venetic extension not actually related to the Po River basin; it runs from the Western Alps to the Adriatic Sea. The flatlands of Veneto and Friuli are often considered apart since they do not drain into the Po, but they effectively combine into an unbroken plain.
