but the further I got into this (at the 17 min mark now) the inside passage of at least one tunnel has seams which could just as easily be seen in the GP. tight with no discernible gaps - starting at the 6 min mark (very clear at the 6:25 mark) and then again at the 11:30 mark. Really large blocks perfectly fitted against/ton top of one another and at angles.

Looks very ancient based on weathering to what would appear to be a quarry but then mixed in with really high quality work inside and on the base stones outside.
Made me think that it could be interesting to scan this mound to see if any cavities of significance and, once again, there are bosses just after the 14 min mark. This simply wasn't done with hand tools - is machined - looking at 15 min mark with closeup side view at 16:27 mark. Geopolymer is what comes to mind. Really cool after the 20 min mark...very fine finishing
