Which river is described as the "last wild river in Western Europe"?

The Loire River is often referred to as the "last wild river in Western Europe" due to its relatively untouched natural environment compared to many other rivers that have been significantly altered by human activities. This designation stems from the fact that the Loire has not been dammed to the extent of other major rivers, allowing it to maintain a more natural flow and ecosystem. The river flows through diverse landscapes, including vineyards and forests, and is home to a variety of flora and fauna. Its unique characteristics have made it a symbol of ecological preservation in Europe, attracting attention for its biodiversity and scenic beauty.

In contrast, the Rhone, Seine, and Tagus rivers have undergone extensive urbanization and engineering projects, including dam constructions and other modifications that have impacted their natural states. These factors contribute to the Loire's reputation as a wild and free-flowing river, distinguishing it from its peers across the continent.
