The Rhine is one of Europe's major rivers, flowing approximately 1,230 kilometers (760 miles) through six countries: Switzerland, Liechtenstein, Austria, Germany, France, and the Netherlands. It originates in the Swiss Alps and travels northward, eventually emptying into the North Sea. The river is an important waterway for trade and transportation. The Rhine is also known for its picturesque landscapes, including vineyards and historic castles along its banks. It serves as a cultural and economic lifeline for the regions it traverses, contributing to the rich history and development of cities like Cologne and Basel.
