Vienna loves the Danube so much that the city now has four water features with the label “Donau”.

• Alte Donau (Old Danube)
• Donau (Danube)
• Donaukanal (Danube Canal)
• Neue Donau (New Danube)

All of it is thanks to the regulation of the Danube river after the city of Vienna and the surrounding region had to put up with frequent flooding. Vienna embarked on works of flood-control engineering in two major periods of construction: 1870 to 1875, and 1972 to 1988.

Once a former arm of the river, the Old Danube is now a crescent-shaped lake that’s been cutoff by “linearization” and straightening of the Danube. A former natural arm of the river, the Danube Canal was regulated for the first time around 1600. Most visitors will encounter the Danube Canal which is best integrated with the city with the appearance of multiple road and rail crossings and the canal’s reach with 7 of the 23 city’s districts. The Danube river proper was completely regulated and straightened during the second engineering period, which also saw construction of the New Danube as a secondary flood channel in parallel with the primary river.
