The longest river of Europe is the River Volga. It flows primarily in a southerly direction through Russia into the Caspian Sea. The second longest is the Danube, flows west to east before entering the Black Sea.
What I find fascinating is that the Danube River used to be the longest river in Europe before the fall of the Iron Curtain in 1989. Since then, the longest river is Volga, with the length of 3,692 kilometres (2,294 miles).When you consider the river Breg as the source, the Danube is 2,888 kilometers (1,794 miles) long.When compared to all the rivers, the Danube is only the 40th longest river in the world.hat I find fascinating is that the Danube River used to be the longest river in Europe before the fall of the Iron Curtain in 1989.
