Ehrenbreitstein Fortress (German: Festung Ehrenbreitstein, pronounced [ˌfɛstʊŋ eːʁənˈbʁaɪtʃtaɪn]), a fortress in the German state of Rhineland-Palatinate, stands on the east bank of the Rhine opposite the mouth of the Moselle, and overlooks the city of Koblenz.
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 which French troops had repeatedly invaded before. The Prussian fortress was never attacked.
Since 2002, Ehrenbreitstein has formed part of the UNESCO World Heritage Site Upper Middle Rhine Valley.
