What I find really amazing is that they built all of what they had by hand and did not have beasts of burden like the OX or Horses.
My question becomes if they built on top of older civilizations structures are archeologist afraid to dig deeper being afraid of damaging whats on
top?
In the video they show some passages into them but were hose discovered or created by archeologists?
Or do they tunnel into these site to find even older relics?
