A collection of images from a 2016 cruise "Castles on the Rhine" aboard Uniworld's SS Antoinette down the Rhine from Basel in Switzerland to Amsterdam in the Netherlands. The Upper Rhine begins in northwestern Switzerland where the Swiss, French and German borders meet. From Basel the river bends in a northerly direction forming the Rhine Gorge an area known as "The Romantic Rhine" containing more than 40 castles and fortresses and many country villages.
