The Po Delta Regional Park in Emilia Romagna, established in 1988, is a protected area that covers approximately 18000 hectares of the Emilia Romagna region. It extends from the Po di Goro and spread over all the historical delta del Po, including the mouths of some other rivers: the Rhine, the Lamone, the rivers, the Drink. The Delta area is given by the progressive deposition of debris from the river Po; This, in the long run, led to the gradual displacement of the shoreline of the Adriatic Sea.
