High above the Rhine opposite Koblenz is the Ehrenbreitstein fortress. This photo was taken from it and shows the city of Konlenz, the Rhine and Mosel. The fortress is reached by cable car and offers a fantastic view of the river.
Jet, did you take that from a cruise boat? Here's one I took from the cable car. There's a lot of people around because it was Saturday morning and there's a huge flea market round the Deutsches Eck.
