Note: The city of Hattingen is situated on the Ruhr River south of Bochum in the district of Arnsberg in the German state of North Rhine-Westphalia. It received its charter in 1396 and became a member of the Hanseatic League. Like many communities in and around the Ruhr district it declined during the Thirty Years' War, but revived vigorously with the industrial revolution of the 19th century thanks to the surrounding coal mines. As an important industrial city it was bombed and heavily damaged in World War II. The ruins of the 13th-century Isenburg Castle remain, as does St. George's Church of 1450 and the former town hall built in 1576, now a museum. The modern city produces machinery, locomotives, and hardware. The 2004 estimated population was 58,000.
