Sweet, these are great. I can really get a feel for how massive these are. How on ‘earth’ did they do it, or maybe that’s that answer, it was not of this current earth, and we struggle to fathom it as we just don’t know the tech back then.... crazy, I would love to know. I wonder if these are dug out quite deep, like trenches. But it’s cut out of rock rather than dug, right?
