Coat of arms of Koblenz, Germany

Koblenz (UK: /koʊˈblɛnts/ koh-BLENTS, US: /ˈkoʊblɛnts/ KOH-blents, German: [ˈkoːblɛnts] ; Moselle Franconian: Kowelenz) is a German city on the banks of the Rhine (Middle Rhine) and the Moselle, a multinational tributary. Koblenz was established as a Roman military post by Drusus c. 8 BC. Its name originates from the Latin (ad) cōnfluentēs, meaning "(at the) confluence". The actual confluence is today known as the "German Corner", a symbol of the unification of Germany that features an equestrian statue of Emperor William I. The city celebrated its 2,000th anniversary in 1992. The city ranks as the third-largest city by population in Rhineland-Palatinate, behind Mainz and Ludwigshafen am Rhein. Its usual-residents' population is 112,000 (as of 2015). Koblenz lies in a narrow flood plain between high hill ranges, some reaching mountainous height, and is served by an express rail and autobahn network. It is part of the populous Rhineland.
