I grew up in Chinnor. We were told that the cross was carved by the people of Chinnor to add a steeple to St Andrews church as viewed and as a snub to Thame.

And to add a little bit of weird history. When I was 11 (so the summer of1980) we were walking the main track just below the cross, decided to have our sandwiches on the cross. But as we approached we could hear chanting, so creeping stealthily we peered through the trees and could see some sort of ritual dancing on the cross. At first we were amazed to see naked women leaping about. But then realizing this was some sort of potential coven, and probably having seen The Wickerman, ran for our lives!
PS on another occasion myself and a friend were on the pathway that runs below, and swear that we were chased by footsteps that followed us, getting faster as we sped up. And we ran when something seemed like an animal keeping pace in the undergrowth. And were told afterwards that it was common knowledge that a ghostly man and his dog had been heard there before, apparently the locals ran lights on the hills during WWII air raids on Oxford, in a hope that any German bombers might have any spare bombs, and think they were over Chinnor/Bledlow/High Wycombe and drop them. And the depressions near these paths that us kids would BMX on our Griftors, before BMX was a thing, were known as The Bomb Craters, and it's claimed a victim of one of these raids was a man with his dog. So had we heard a spectral man and his dog?
