I looked it up before 18 hours was up. I didn't go there as I spent time in pubs instead of art museums. i guess my cultural stuff is meeting the locals over a few pints of Tennents.
sleepchef didn't, but I was born in that neck of the woods and lived a couple of towns upriver. I bet you are looking forward to putting in some clues, perhaps with song references. If nobody guesses it then I'll answer but I kind of feel like I'm cheating if I were to answer it right away.
I understand your last post now (had to google the song to see if Mr. BACHARACH had sung it), so before I named it I searched my picture archive in Lightroom and found an appropriate next picture to post.
The town in your picture is Bacharach am Rhein. I used to work in Wiesbaden and we would frequently get visitors from headquarters in the USA, which meant I got to take them on castle and wine tasting tours at company expense so I've been to Bacharach many a time. The infamous "Loreley" bend in the Rhine is just downriver.
