Priests we think of as "ancient Egyptians" told Greek wise men about underground chambers from "the first builders" who aligned their hidden labyrinth over 20 degrees off from the pyramid above... Sounds like in very ancient times (before the last pole shift) civilization wasn't aligning structures with our current North Pole. Which is why I suggest reading books like Hancock's Message of the Sphinx and my own POLE SHIFT: Evidence Will Not Be Silenced
