Just revisiting this and having a proper read through again. I think when originally posted, for those of us who had it fresh in our mind it was a case of, "of yeah that's pretty much it", but reading it back again now I can appreciate, a: just how much of an excellent account of the place this report is, and b: how stunning the place actually was to visit. Your sentiments in the very first paragraph regarding the scale of the place and wonderment as to how they could even build such a place, numerous years on, is most certainly my takeaway thought from this. A rare treat for urban explorers nowadays unfortunately, and it will most certainly be all the more saddening when the remaining few inevitably close.
