Brook, do these wall drawings look similar to the ones you've seen in the Voynich Manuscript? (They do, to me.) These are from Spain, maybe near the original spot of Knights Templar, maybe before they went berserk, Mary Magdalene, etc. It is a secret spot, anyway.
There's supposed to be a portal there, too.
