The Rhine
The Rhine River
The Rhine, at 1,320 km (820 miles) long, is one of the longest rivers in Europe, and has been important as a commercial waterway for at least 2,000 years.  The many castles along its banks established control over portions of the river primarily for the purpose of collecting tolls.
Rüdesheim am Rhein
Rüdesheim (or Ruedesheim) is located on the east bank of the Rhine at the southern entrance to the Loreley valley.
Rheinfels Castle
Rheinfels Castle above St. Goar bills itself as "for 500 years the largest and most imposing castle on the Rhine".  Much of the castle was converted to ruins in 1794, but the remains still impress all who tour the site.
Marksburg Castle
Marksburg Castle, on a hill high above Braubach, has survived for over 700 years and is the only hill castle on the Rhine that has never been destroyed.  Visits here make the river control and defensive functions of these castles very clear.
The Moselle River joins the Rhine in what is now the city of Koblenz, at what is known as the German Corner.  The strategic importance of this location was recognized as early as 1000 BC.
