Always keeping discovering new stone structure

Just came across this piece about megalithic structure in Russia ! http://www.minds.com/blog/view/290189665556762624/newly-found-megalithic-ruins-in-russia-contain-the-largest-blocks-of-stone-ever-discovered

I hope our Floating stone staircases will be still standing in 1000 years to come ! And that we will outlast the concrete cast product !
