Devil’s Stone

Chunky stone by the oak and just outside the churchyard. Usual stories by the locals about the Devil trying to throw/carry it elsewhere. Also said that it is a “Sarsen” ie. a foreign stone and not from the immediate area. I’m not a rock expert but it looks to me as being a granite with a pinkish hue. Are there any sources close by? The oak is pretty venerable and has been looked after well including the rotten core being filled with concrete.
Apparently it takes about a dozen guys with crowbars to flip the stone on Nov. 5th.
