Identifying a mystery location

 I have begun to scan photos borrowed from my mom's house (really they are all just boxed items she is going through from grandma's, they are not necessarily "hers") and trying to be clear about what things are and who is in each photo. This is a bit of a challenge because my mountaineering grandparents visited a lot of pretty places that look much alike. Also some of the sets of photos are clearly reprints, and removed from the original contexts (what pictures would have been in the same set with them indicating being taken at the same time, etc) makes it harder to guess! This photo stood out from the set I was scanning and I wondered why.

Before you begin to guess, we were able to figure out this location. My crack collection of knitting pals over the internet were able to ID the location as being the Dinant Citadel of Namur, in Wallonia, Belgium, as taken from the Jambes bridge over the Meuse. (Apparently this is THE location to photograph the citadel, as many photos from the web have the exact angle.) This photo has led me on a great journey of information since identifying it, for instance this river has been a strategic location since Roman times and there were significant battles here in World War 1 and 2. In fact, the Meuse was part of the forest of Ardennes which was thought to be impenetrable to tanks, and where the Battle of the Bulge was fought. I have, through family stories, been told that when my Grandfather served in WW2 it was as part of this campaign (thought he was a Technician and lucky enough not to have to fire his rifle). 

In searching for more information about this location and the War(s), I learned that this location suffered heavy damages and wondered what that meant for dating the photo. The current bridge (Pont Jambes) is made of stone and has large arches to allow boats to pass, constructed in 1961. The Wikipedia entry for the Battle of Dinant (first World War) shows the destruction of the buildings at the base of the citadel as well as another bridge that would probably be located out of the photo to the right, by the church building, indicating significant damage to the whole area. I can't tell anything about the materials or permanence of this bridge based solely on this photo, so the best guess for era would probably involve getting lucky and finding images that had the same perspective and matching the buildings in the background. The reason I am interested in the date of the picture is I am curious if it is a photo taken concurrently with my Grandfather's service, or if he (or someone else) returned and took it at a later date. Unfortunately my Grandfather passed when I was quite young, and while he did come and speak to my elementary school class about his service, I really don't remember much of his words, and what I do remember are mainly reinforced by 2nd hand accounts from other family members. So, we figured out part of the mystery of this location, but more remains to be learned!
