I’ve never seen these pictures of the ancient Druid Temples I did a research on them in writing :Boudica or Boudicca: Queen of the Iceni”. There’s information to be found on them but not all in one place. One will have to research records as far east from Britannia as German and pushing into Asia Minor. The Greek, Egyptians, and Macedonians wrote about them and their wisdom regarding nature.
The picture with the supposedly demon head appears to be a recent add on. It isn’t aged to match it’s surrounding. But nonetheless, the place definitely looks creepy enough to be haunted.
