Rheinau (German pronunciation:[ˈʁaɪnaʊ]; Low Alemannic: Rhinai) is a city in southwestern Baden-Württemberg, Germany and is part of the district of Ortenau. It is situated directly on the Rhine River, which forms the border with France, approximately 10 kilometers north of Kehl and 15 kilometers east of Strasbourg. The modern municipality was established in 1975 through the merger of nine former independent villages, including Freistett, Helmlingen, and Rheinbischofsheim. Rheinau is known locally for its annual asparagus festival (Spargelfest), reflecting the region's agricultural tradition of cultivating white asparagus.
