"Dortmund is a city in Germany. It is located in the Bundeslan of North Rhine-Westphalia. Its population of 587,830 (in June 2005) makes it the 8th largest city in Germany and the 34th largest in the European Union.
Cultural history tones are set by the churches in the city centre whose towers characterise the skyline of Dortmund. The Reinoldikirche and the Marienkirche are gems of medieval architecture.
The city centre of Dortmund still retains the outline of the medieval city. A ring road marks the former city wall, and the Westen-/Ostenhellweg, part of a medieval salt trading route, is still the major (pedestrian) street bisecting the city centre." - in: wikipedia
