I’ve visited the Castle a couple of times. Awesome is the word. It is as strange as you will allow it to be. Truly amazing. Being a geologist/geophysicist, and one who researches “paranormal” everything, and having carefully, respectfully made my way around the Castle, sat in the chairs and on the benches, laid on the bed, breathed and gotten still, I guard against letting imagination run loose, but I know one place where the energy is so palpable it is difficult to maintain balance when standing on it. Imagination? Possibly. It is such a strange place it is easy to let imagination run wild.
I am convinced the history of ley lines has some truth and value, I suspect people more sensitive to these subtleties can actually feel the subtle powers involved.
Most of us love a mystery. I pay attention to allowing the mystery remain a mystery until hard facts mess it up by offering believable explanations, so I let it be, and observe.
