The Neckar (German pronunciation: [ˈnɛkaɐ̯]) is a 367-kilometre-long (228 mi) river in Germany, mainly flowing through the southwestern state of Baden-Württemberg, with a short section through Hesse. The Neckar is a major right tributary of the Rhine. Rising in the Black Forest near Villingen-Schwenningen in the Schwenninger Moos conservation area at a height of 706 m (2,316 ft) above sea level, it passes through Rottweil, Rottenburg am Neckar, Kilchberg, Tübingen, Wernau, Nürtingen, Plochingen, Esslingen, Stuttgart, Ludwigsburg, Marbach, Heilbronn and Heidelberg, before discharging into the Rhine at Mannheim, at 95 m (312 ft) above sea level.
From Plochingen to Stuttgart the Neckar valley is densely populated and industrialised, with several well-known companies, e.g. Daimler AG (the maker of Mercedes Benz cars) and Mahle GmbH being located there. Between Stuttgart and Lauffen the Neckar cuts a scenic, meandering, and in many places steep-sided, valley into fossiliferous Triassic limestones and travertine. Along the Neckar's valley in the Odenwald hills many castles can be found, including Hornberg Castle and Guttenberg Castle in Haßmersheim; the now-mothballed Obrigheim Nuclear Power Plant and the active Neckarwestheim Nuclear Power Plant are also located there. After passing Heidelberg, the Neckar discharges on average 145 m3/s (5,100 cu ft/s) of water into the Rhine, making the Neckar its 4th largest tributary, and the 10th largest river in Germany.
