Sail along the beautiful Rhine Valley this morning with its forty castles strung along the river banks. Rüdesheim has a long history going back to Roman times, as do most coastal cities along the Rhine. The town is famous for, among other things, its long avenue of shops and wine bars, the Drosselgasse, and also the impressive Niederwald Monument commemorating the unification of Germany as well as the Siegfried's Mechanical Music Museum.
