Koblenz (pop. 107,825), also spelled Coblenz, is an administrative, trade, and tourist center on the Rhine River in western Germany.
The Moselle River empties into the Rhine River at Koblenz at a point of land called Deutsches Eck. The German Federal Archives are in Koblenz. One of the oldest German communities, Koblenz began as a Roman fort around 9 B.C. The Ehrenbreitstein Castle, a popular tourist attraction in Koblenz, was built sometime between A.D. 900 and 1100, destroyed in 1801, and rebuilt from 1816 to 1832. The old town center of Koblenz was destroyed during World War II (1939-1945), but was restored in its traditional style.
