The mouth of the small River Lune, a tributary of the Weser, is situated between Luneort Airport and Luneplate Island, a piece of marshland resembling similar formations in Holland. Luneplate was created during the Christmas flood of 1717. Later inundations (mainly in early 20th century) continued to alter the shape of the island. There had been plans made to turn the island into a large industrial area even before World War One. A port for timber trade for Bremerhaven and Geestemünde was envisaged. In the 1920s, the extension of the fishery port area towards Luneplate was under discussion. In 1939, the area was designated as a new industrial and fishery port and as a naval base. Later, in the 1960s, the plans for industrialization re-emerged and led to an agreement between the federal states of Bremen and Lower Saxony on October 18th 1979. One of the projects considered was the construction of a petrochemical plant.
But all these plans came to nothing and Luneplate has retained its unspoilt nature. Moreover, some conservancy measures were enforced as compensation for the marshland used for the new container terminal to the north of Bremerhaven (CT 4).
