Nordenham () is a town in the Wesermarsch district, in Lower Saxony, Germany. It is located at the mouth (on the west bank) of the Weser river on the Butjadingen peninsula on the coast of the North Sea. The seaport city of Bremerhaven is located on the other side (east bank) of the river. The Midgard-seaport in Nordenham is the largest private-owned harbor in Germany. Geography Geographical location Nordenham is located on the West Bank of the Weser River across from Bremerhaven along the river's mouth at the North Sea, north of the cities of Bremen and Oldenburg. The local environment is mainly marshland, specifically Marsch oder Schwemmland. Boroughs Nordenham is composed of 35 districts, each with a long history as a separate community: Abbehausen, Abbehauser Groden, Abbehauser Hörne, Abbehauserwisch, Atens, Atenserfeld, Blexen, Blexersande, Blexerwurp, Bulterweg, Butterburg, Einswarden, Ellwürden, Enjebuhr, Esenshamm, Esenshammer Altendeich, Esenshammer Oberdeich, Esenshammergroden, Friedrich-August-Hütte, Grebswarden, Großensiel, Havendorf, Heering, Hoffe, Kloster, Moorseersand, Oberdeich, Phiesewarden, Rahden, Sarve, Schockumerdeich, Schweewarden, Schütting, Tettens, Treuenfeld, and Volkers. Two nearby islands are also part of the town: Langlütjen I und Langlütjen II. History Nordenham evolved from the town of Atens due to the efforts by merchant Wilhelm Müller who traded cattle and sheep to England in the late 19th century. Some of the oldest parts of the modern town area are the old villages or Wurtendörfer (roughly translated as 'terp villages') Blexen, Einswarden and Atens. Bishop Willehad, the Northumbrian-born missionary of the Frisians, died in Blexen in the year 789, which is also commonly accepted to be Blexen's year of foundation. In 1407, the Vredeborch or Friedeburg (to be translated as "peace castle") was erected by the Hanseatic city of Bremen, a castle (although it was probably more a kind of large fortified house) to protect interests against the rebellious inhabitants, the Rüstringer Frisians. The stronghold was destroyed in 1425 and it is possible that the site was later used by a monastery. Nordenham's town founder Wilhelm Müller later built his farm house and a restaurant on the same site. In 1959 those were demolished and the still existing community hall was built there. The town hall was built in 1953 and moved into by the local authority in January 1954. Between 1499 and 1514, the area was conquered by the County of Oldenburg and in 1813 by the French emperor Napoleon, whose army shot ten local inhabitants at the church in Blexen.
