The Rhine
From the Alps to the North Sea
▶ Play it onlineThe Rhine has organised European settlement, trade and war for two thousand years, and this plate shows why without drawing a single national border. The Alps sit white and high in the south, the basin opens northwest, and the great tributary pieces fan out from the main stem like a leaf. Children who know the Rhine only as a line on a school map are usually surprised by how much of Europe belongs to it.
What a child works out
- One river system can cross six countries and not care.
- The Alps are where the water starts; you can feel the drop.
- Names on a map — Mosel, Neckar, Main — turn out to be places, not just words.
