Map of Byzantine Constantinople. The Neorion is located in the eastern part of the city, on the southern shore of the Golden Horn, near its mouth into the Bosphorus

The Neorion Harbour (Greek: Λιμὴν τοῦ Νεωρίου or Λιμὴν τῶν Νεωρίων) was a harbour in the city of Constantinople, active from the foundation of the city in the 4th century until the late Ottoman period. It was the first port to be built in Constantinople after its re-foundation by Constantine the Great, and the second in the area after the Prosphorion, which was the port of ancient Byzantium.[1] [2]
