The Port of Mainz (or Mainzer Hafen in German) is the port of Mainz, Germany. Lying on the western bank of the Rhine river, it has a long history reaching back through the Middle Ages to Roman times. The modern port facilities, existing for approximately 120 years in their general environs, are located mostly to the north of the city proper, and will be extended to the north of their current location during the coming years to make space for a new residential area.[1]
