Giessen, spelled Gießen in German (German pronunciation: [ˈɡiːsən]), is a town in the German federal state (Bundesland) of Hesse, capital of both the district of Giessen and the administrative region of Giessen. The population is approximately 76,000, with roughly 24,000 university students.
The name comes from Giezzen, as it was first referred to in 1197, which refers to the position of the town between several rivers, lakes and streams. The largest river in Giessen is the Lahn, which divides the town in two parts (west and east), roughly 50 kilometres north of Frankfurt am Main.
In 1969, the town hosted the ninth Hessentag state festival.
Giessen came into being as a moated castle in 1152, built by Count Wilhelm von Gleiberg, although the history of the community in the northeast and in today's suburb called "Wieseck" dates back to 775. The town became part of Hesse-Marburg in 1567, passing to Hesse-Darmstadt in 1604. The University of Giessen was founded in 1607. Giessen was included within the Grand Duchy of Hesse, created in 1806 during the Napoleonic Wars. After World War I, it was part of the People's State of Hesse.
During World War II, a subcamp of the Buchenwald concentration camp was located in the town. Heavy bombing destroyed about 75% of Gießen in 1944, including most of the town's historic buildings. It became part of the modern state of Hesse after the war.
An American military base was located in Giessen after World War II. The U.S. Army Garrison of Gießen had a population of 500 Americans. The base is a converted German Army Air Field, which is reflected in some of the buildings, including the housing area. A theatre, known as the Keller Theatre, is a converted German army Officer's Club. As of September 28, 2007, the Giessen Depot, and all other communities in the greater Giessen area were turned back over to the local German authorities.
