Koblenz, Germany

Koblenz is a German city of roughly 114,000 residents at the point where the Moselle flows into the Rhine, a headland known as the Deutsches Eck that carries a 37-metre monument to German unification first raised in 1897 and rebuilt in 1993. The Romans founded the settlement in 9 BC as Castellum apud Confluentes, and its oldest church, the Basilica of Saint Kastor, dates to 1056. Above the river stands the Ehrenbreitstein Fortress, built between 1817 and 1828 over earlier defences and ranked among the largest surviving fortifications in Europe. The Pfaffendorf Bridge, completed in 1864, was the first railway crossing of the Rhine here.
