Salzgitter is an independent city in southeast Lower Saxony, Germany, located between Hildesheim and Braunschweig. Together with Wolfsburg and Braunschweig, Salzgitter is one of the seven Oberzentren of Lower Saxony. With 101,079 inhabitants and 223.92 square kilometres (86.46 sq mi), its area is the largest in Lower Saxony and one of the largest in Germany. Salzgitter originated as a conglomeration of several small towns and villages, and is today made up of 31 boroughs, which are relatively compact conurbations with wide stretches of open country between them. The main shopping street of the young city is in the borough of Lebenstedt, and the central business district is in the borough of Salzgitter-Bad. The city is connected to the Mittellandkanal and the Elbe Lateral Canal by a distributary. The nearest metropolises are Braunschweig, about 23 kilometres to the northeast, and Hanover, about 51 km to the northwest. The population of the City of Salzgitter has exceeded 100,000 inhabitants since its foundation in 1942, when it was still called Watenstedt-Salzgitter. Beside Wolfsburg, Leverkusen and Eisenhüttenstadt, Salzgitter is one of the few cities in Germany founded during the 20th century.
