The Danube Canal (Donaukanal in German) is an artificial waterway that branches off from the main Danube River. Starting at Kahlenberg in Vienna, it flows through the city before rejoining the Danube south of Vienna. Construction began in 1718, initially designed for navigation and flood control, but over the years, it has served various other purposes as well.
The canal was originally developed to allow vessels to transport goods and connect to other parts of Europe via the Danube River. But as the city developed, its role as a commercial shipping route reduced and made it more of an urban settlement.
