Reminds me of an anecdote from my wife's uncle, who has a such a site on his land (also somewhere in Ireland, I'll not get too specific!), a burial site covered with a large stone. He told some researchers in the university about it and they had a field trip to study it. The professor was very excited about it as the orientation of the stone confirmed some theory of his, to which my wife's uncle whispered to one of the students that out of curiosity he had actually lifted and replaced the stone with a JCB not necessarily in the same place at all. The student's advice was 'don't tell him, it would only disappoint him.'
