If we all got quietly wiped out tomorrow, I wonder how long it would take for the Burj Khalifa to fall down. Probably less than 3800 years. Then maybe some older, shorter, stronger skyscraper in a geologically stable zone would take the crown for a while.

In the long run though, I suspect the solid stone construction and ultra stable shape of the Great Pyramid would see it regain the title and keep it for hundreds of thousands of years until it blew away.

Interesting to speculate about, anyway. Let us hope we all live forever.



I think anything made of steel and concrete would crumble within a couple of centuries, without maintenance. The rebar would rust.

Maybe the stone cathedrals would last longer?

In any case, the biggest man made structure would probably be an open-cast mine or a slag heap.
