Hmm, I was in Bosnia/Herzegovina, Croatia and Slovenia this past summer, and saw many "spomenik"[0]... It is interesting to see these in person and their size is usually surprising. If you are traveling in the area there's a site dedicated to cataloguing the location & appearance of these monuments.[1]
