At first sight you might be mistaken in thinking that this is an glimpse into the future of Earth, it could even be an advanced civilisation on a distant planet and yet, these images are of structures in the former Yugoslavia. Created during the 1960’s and 1970’s, they were the idea of Josip Broz Tito the President at the time. The idea is that sites where battles in WWII took place or where concentration camps were built, should be commemorated. However, during the 1990’s Yugoslavia became Serbia, Montenegro, Slovenia, Croatia, Macedonia and Kosovo the monuments were abandoned and reasons for them being there were forgotten. Yet, after all this time they remain and are still stunning to look at. For more information on these monuments, go to the Crack Two website where there are more images available.
