Such a culture could have been abhorred by others, maybe enemies, and these other people may have decided to either destroy the temples or bury them in a mound of dirt.
But what did eventually happen to this culture? Did it die out or did it move elsewhere to continue some form of their practise?
Then I had to think of the Parsi, Zoroastrians, who still give their dead a socalled open air burial which means they put their dead on a high and artificial platform, a circular temple on some mound or mountain:
I think it was some 30+ years ago when I watched a black&white documentary about their burial practice. It was a gloomy, creepy, and dark movie, stuff nightmares are made of: a corpse was brought into a circular building, a guy butchering the corpse into smaller pieces, and then masses of vultures fighting with eachother to get the most juicy pieces.
But these Zoroastrians are of much more recent times, right?
Well, the ancients thought differently:
