On the luncheon plates in the Ralph Stevenson & Sons "Cologne" pattern, the meandering river starts in the foreground and winds almost vertically through the center of the view toward distant mountains.  Along the way, we are treated first to romantic natural woodland scenery, then an architectural complex a bit further on complete with walls and watchtowers.
