Well, the title of a little misleading, as there was no wedding. But this could be the view of a wedding, as this image was taken from the highest floor in the Hochzeitsturm (English: wedding tower) in Darmstadt. So, if you are willing to take some stairs (or a small elevator), you could have this view through one of the small windows during your wedding.
