Ehrenbreitstein Fortification (Festung Ehrenbreitstein) is a fortress on a hill on the east bank of the Rhine opposite the city of Koblenz in the German state of Rhineland-Palatinate. Occupying the position of an earlier fortress destroyed by the French in 1801, it was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1828 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The Prussian fortress was never attacked. Since 2002, Ehrenbreitstein has been part of the UNESCO World Heritage Site Upper Middle Rhine Valley.
