There could be a "Polygonal" Pyramid hiding underneath Borobudur, Java.
There would seem to be a polygonal pyramid hiding underneath Borobudur in Java. This is evident from various pathways which look quite bizarre. A caveat is that Unesco repaired the crumbling site in 1973, possibly altering its appearance, but this we do not know. The structure underneath would have taken the form of a polygonal platform, possibly.
