The harbour basin of the Old Port in Lüneburg dates back to the 13th century and is directly adjacent to the Lüner Mühle and the Abtsmühle. As the harbour used to be an important hub for the transport of goods by ship, it was well developed. For example, a bridge led across the harbour basin to the Lüner Tor, so that carts could also leave the town without any problems. From the end of the 14th century, precious salts were shipped to Lübeck and Hamburg via the Ilmenau, the Elbe and the Stecknitz Canal. The fleet anchored in Lüneburg comprised about 100 ships. Two replicas can be seen in the harbour today.
