The city of Koblenz is one of the most ancient German cities. For, in 1992 it celebrated the bi-millennium from its foundation.
Its name is Latin in origin, it comes from "Confluentes" (flow together) owing to its geographic position. Koblenz is situated where the Rhine joins the Moselle , the so-called the German corner.

In 1897 the Keiser William I was honoured with a giant equestrian statue. Since 2002 some sites of the city are part of the UNESCO heritage, since they are located in the middle valley of the Rhine, as well as the castle of the city since 2005.

In 830, because of some uprisings among Louis the Pious' children, the reign underwent a further subdivision and passed to Charles the Bald in 837.
Today Koblenz comes third in number of its inhabitants, about 110.000, of the Rhineland-Palatinate cities after Mainz and Ludwigshafen.
