Hattingen is located on the south bank of the Ruhr in western Germany. It was first mentioned in documents in 1396, when the Duke of Mark granted permission to build a city wall. Today Hattingen is a tourist draw because of its historic district with Fachwerk (timber-framed houses) built between the 14th and 16th centuries. The old part of the city is still surrounded by the city walls today. There are about 55 000 people living here. Back in 1720, there were 52 operating coal mines in the area and Hattingen became one of the first industrial cities in the region. Steel production started in 1853. This lasted until 1987, when the steel factory was shut down.
