Map - Lauenburg (Elbe) (Lauenburg/Elbe)

Lauenburg, or Lauenburg an der Elbe (Lauenberg on the Elbe), is a town in the state of Schleswig-Holstein, Germany. It is situated on the northern bank of the river Elbe, east of Hamburg. It is the southernmost town of Schleswig-Holstein and belongs to the Kreis (district) of Herzogtum Lauenburg.

The town was founded in 1182 by Bernard of Ascania, the ancestor of the Dukes of Lauenburg. It took its name from that of the castle of Lowenborch (erected here between 1181 and 1182), deriving from Lave, the Polabian-language name of the Elbe (compare modern Czech Labe). Saxe-Lauenburg was a duchy until 1 July 1876, when it was incorporated into the Royal Prussian Province of Schleswig-Holstein. Lauenburg served as the ducal capital until 1616, when the castle burnt down. In 1619 the capital was moved to Ratzeburg. The area of the duchy was roughly identical with that of today's district. In medieval times Lauenburg was a waypoint on the Old Salt Route, while today it is the southern terminus of the Elbe-Lübeck Canal.

Following the Napoleonic Wars, Lauenburg was ceded by Prussia to Denmark in exchange for the region of Pomerania.

Between 1945 and 1982 Lauenburg served as West German inner German border crossing for cars travelling along Bundesstraße 5 between the Soviet Zone of occupation in Germany (till 1949), thereafter the East German Democratic Republic, or West Berlin and the British zone of occupation (till 1949) and thereafter the West German Federal Republic of Germany. The traffic was subject to the Interzonal traffic regulations, that between West Germany and West Berlin followed the special regulations of the Transit Agreement (1972).
