The scenery of the Rhine began to get better after entering Germany. In the 65-kilometer-long Middle Rhine Valley of Germany, there are many ancient towns and castles. These stormy castles and unpretentious towns are scattered between the rolling hills on the banks of the Rhine, witnessing the passing of time. The German aristocrats, princes, and archbishops of the Middle Ages fought for their hegemony. They converted the personal collections of the kings to their own hereditary property. They dug trenches, set up territories, and occupied the terrain to build their own castles. Hundreds of years of historical ruins make the Rhine Valley a unique landscape that blends natural beauty with culture and art. In 2001, the middle and upper reaches of the Rhine River were selected as World Cultural Heritage, and today it has become an important tourist route in Germany. In 1802, the German writers Clemens von Brentano and Achim von Alnim walked from Cologne to Koblenz for a romantic journey to the Rhine. Collect folk songs and legends about the Rhine River, organize them into poems, make the Rhine a beautiful fairy tale world, and present the beautiful fairy tale here to the world in the form of poetry. Koblenz, the city is located at the confluence of the Moselle and the Rhine, historically an ancient Roman town. In the sixth century AD, it was the royal residence of the Frankish family. It was destroyed during the Second World War. The historic buildings were restored after the war, and the new builders had a modern form. The lake outside the city is beautiful and the tourism industry is quite prosperous. It is a famous white wine Riesling production area.
