The 'Neckar' is a 367 km long
river, mainly flowing through the southwestern
state of
Baden-Württemberg, but also a short section through
Hesse in
Germany, a major right tributary of the
River Rhine, which it joins at
Mannheim. Rising in the
Black Forest near
Villingen-Schwenningen in the conservation area ''Schwenninger Moos'' at a height of 706 m above sea level, it passes through
Rottweil,
Rottenburg,
Tübingen,
Nürtingen,
Esslingen,
Stuttgart,
Ludwigsburg,
Marbach,
Heilbronn and
Heidelberg, before discharging into the Rhine at Mannheim (at 95 m above sea level).
Along its valley in the
Odenwald hills, many castles can be found, like and in
Haßmersheim, but also the closed
nuclear power station which is due to be dismantled by 2023. After passing Heidelberg, the Neckar discharges on average 145 m³/s of water into the Rhine which makes the Neckar its 4th largest tributary, and the 10th largest river in Germany.
The name ''Neckar'' was derived via ''Nicarus'' und ''Neccarus'' from
Celtic ''Nikros'', meaning ''wild water'' or ''wild fellow''. Since about 1100, Black Forest wood was transported by
timber rafting, e.g. to Holland for the use in
shipyards. During the 19th century, traditional
horse-drawn boats were replaced by steam boats that used a 155 km long chain in the river to pull themselves upstream. The railway made it possible to transport timber to the port of Heilbronn, limiting timber rafting to the lower part of the Neckar after 1899. Due to 11 locks, ships up to 1500t could travel to Heilbronn in 1935. By 1968, the last of 27 locks, at Deizisau, was completed, making the Neckar navigable for
cargo ships about 200 km upstream from Mannheim up to the river
port of
Plochingen, where the
Fils joins and the Neckar bends, taking a Northwestern instead of a Northeastern direction. The other ports are in Stuttgart, Heilbronn and Mannheim.
The river's course provides a popular route for cyclists, especially during the summer months. Its steep valley sides are used as
vineyards, to cultivate mainly
Trollinger.
