Schwäbisch Hall is a city in the German state of Baden-Württemberg and capital of the district of Schwäbisch Hall. The city is located in the valley of the Kocher river in the north-eastern part of Baden-Württemberg. Hall was a Free Imperial City for five centuries until it was annexed by Württemberg in 1802. In 1960, Schwäbisch Hall reached the status of a Große Kreisstadt. This means that the city took over some tasks of the district.[6] From the end of World War II until the end of the Cold War, Dolan Barracks and Schwäbisch Hall Army Air Field was a kaserne which hosted a series of US Army aviation units and ordnance units until it was turned back over to German control in 1993.
