The picture below shows the city of Heidelberg and the "old bridge" at the lower right. The above picture was taken from the right hand side of this picture on the opposite side of the Neckar very near the old bridge. If you count the bridges from lower right to upper left there are four in the picture but the fourth is very difficult to see. I live just ast the right hand end of the fourth bridge (within about 100 yds). The tall buildings at the end of the fourth bridge are part of the university complex.
