What they are doing is completely insane!
Why not build an exact replica of the original !?
Repairing rocks and old restoration mistakes omg they are unbelievably crazy they could make a brand new building exactly as it was at its prime complete with new sculptures and art.I understand preserving the original but making another exactly to same specifications would be preserving it also.I dont know 100 million and 30 years is hard to imagine, they could have built a pyramid!Greeks would be laughing they would tear it down and rebuild it.
