Koblenz (French: Coblence) is the third largest town on the Rhine River after Mainz and Ludwigshafen and is located in the State of Rhineland-Palatinate. It is also one of the oldest cities in Germany. Koblenz is a university town and is in the northern part of the Rhineland-Paltinate. Koblenz is part of one of the five Metro-Plexes in the State of Rheinland-Pfalz. It is also the county seat for Mayen-Koblenz, home of the Struktur- und Genehmigungsdirektion Nord Administration, and the State Supreme Court.

The name Koblenz is derived from the Latin word “confluents” (flowing together), because the Rhine River and the Mosel River come together here and form the Deutsches Eck (German Corner). Until 1926, the name was spelled Coblenz. In 1992, Koblenz celebrated its 2000th anniversary. In 1962, Koblenz officially became a city with more than 100,000 citizens.

The next largest cities are Bonn, about 60km (37 miles) north along the Rhine and Mainz about 90 km (56 miles) south along the Rhine. Since 2002, parts of the city are part of the World Culture Inheritance Famous City (Oberes Mittelrheintal) as declared by UNESCO.

Koblenz is situated at the Deutsches Eck, where the Mosel und Rhine rivers flow together. The city is at the foot of the Hunsrück mountains and borders the hilly countryside of the Maifeld (the Eifel). The parts of the town to the right of the Rhine River border on the Westerwald, which reaches all the way to the river with extremely steep declines. The southern part of the city, i.e., the section lying between the two rivers, is partly covered with trees and forms the “Green Lung” of the city. This part of the Rhine belongs to the “Mittelrhein” or Middle Rhine area.
