Amazing RHINE River
The Rhine is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Franco-German border, then flows through Germany and eventually empties into the North Sea in the Netherlands. It is also the border between Switzerland and Liechtenstein and also the border between Germany and France. It runs through Basel, Bonn, Cologne and Duisburg. It also separates the cities of Mainz and Wiesbaden.
The river runs only into one lake on its way, this is Lake Constance that is on the border of Switzerland, Germany and Austria.
It is the twelfth longest river in Europe
The Rhine and the Danube formed most of the northern inland frontier of the Roman Empire and, since those days, the Rhine has been a vital and navigable waterway carrying trade and goods deep inland. It has also served as a defensive feature and has been the basis for regional and international borders. The many castles and prehistoric fortifications along the Rhine testify to its importance as a waterway.
