Padborg (German: Pattburg) is a Danish border town with a population of 4,455 (1 January 2014) located on the border with Germany. It is the location where both the E45 motorway, a railway and the historic Danish Army Road, hærvejen, cross the border. Located a few kilometres northwest of Schleswig's historic commercial centre, Flensburg, Padborg was a small settlement when the region returned to Danish rule in 1920 following a plebiscite, but grew rapidly in size after the establishment of the current border. It is a transport centre and railway town. When the border was established in 1920, the originally planned border line was moved c. 200 metres south of Padborg in order to allow construction of the railway station and a customs office.
