The above navigable image is a 1986 Yugoslav map of the memorials (spomeniks) to the National Liberation War (WWII). It was graciously provided to me courtesy of Jan Kempanaers.

It is not clear how many of these still exist or have been destroyed or forgotten over the years. The legend for this map, in the lower-left hand corner of the image, is translated here (with clickable links):
