I'm surprised we haven't seen more sci-fi and post-apocolyptic movies featuring these places. They must be incredible to see in person.

These structures were commissioned by former Yugoslavian president Josip Broz Tito in the 1960s and 70s to commemorate sites where WWII battles took place.

In the 1980s, these monuments attracted millions of visitors per year, especially young pioneers for their "patriotic education." After the Republic dissolved in early 1990s, they were completely abandoned, and their symbolic meanings were forever lost.
