The Rijn, or Rhine, is one of Europe's major rivers, flowing through six countries: Switzerland, Liechtenstein, Austria, Germany, France, and the Netherlands. It stretches approximately 1,230 kilometers (760 miles) and is known for its historical significance and economic importance, serving as a vital waterway for trade and transportation. The river originates in the Swiss Alps and travels northward, eventually emptying into the North Sea. Along its banks, the Rijn is lined with picturesque towns, vineyards, and castles, making it a popular destination for tourists. It also plays a crucial role in the region's ecology and culture.
