And, so it was with the Neckar river, along which the city of Heidelberg was established. This 225 mile long waterway, a major tributary of the Rhine River, and the fourth largest in Germany, allowed for Black Forest timber, harvested at the river’s source 2100 feet above sea level, to be rafted downstream to markets since the 1100’s.
The word “Neckar” derived from the Celtic “Nikros” meaning “wild warer.” Boats drawn along the Neckar by horses in earlier centuries were replaced by steam-powered chain boats (a 110 mile long looped chain system laid in the river to provide propulsion for the boats) during the 19th century. A series of 27 locks allowed cargo ships to traverse 120 miles up the Neckar from the Rhine River. By the end of the 19th century, timber transportation was accomplished by railroads (faster and cheaper) rather than along the River.
During the Middle Ages, German royalty had built castles above the river ‘s banks, ostensibly to protect merchant ships from pirates...for a toll, of course. The actual existence of pirates along the Neckar was always in question, but that did not prevent the collection of the tolls (capitalization at work). Today, tourist boats exploring the many historic castles of the Neckar far outnumber cargo vessels.
