After scenic cruising the Middle Rhine viewing castles all morning, we arrived at Koblenz, Germany. After lunch we toured Marksburg Castle, and then had a walking tour of the old town before dinner.
Click on the following Marksburg Castle photo to view the Koblenz photo gallery (about 42 photos) at my SmugMug photo web site.
The automatic slideshow displays each photo for 2 seconds with a 1 second fade transition. There are options for full-screen mode in the lower-right corner, and a pause button in the lower-left corner. There are also arrows on the left and right sides to move manually forward and backward through the photos.
