Lahr is a city in western Baden-Württemberg, Germany, approximately 50 km north of Freiburg in Breisgau, 40 km south east of Strasbourg, and 95 km south west of Karlsruhe. It is the second largest city in Ortenau (district) after Offenburg, and serves as an intermediate economic centre for the cities and towns of Ettenheim, Friesenheim, Kappel-Grafenhausen, Kippenheim, Mahlberg, Meißenheim, Ringsheim, Rust, Schuttertal, Schwanau and Seelbach. The population of Lahr passed the 20,000 mark in the mid-1950s. When the new body of Municipal Law for Baden-Württemberg came into effect on April 1, 1956, the city was therefore immediately accorded Große Kreisstadt status. In addition, Lahr cooperates with the town of Kippenheim in administrative matters.
