This is the Hawk Stone, near Dean, Oxfordshire - a Neolithic oolitic limestone standing stone - according to Wikipedia, local legend has it that the stone was used for burning witches - the cleft in the top was made by the chains used to tie them up.

I was not aware of the connection to witches until after I had looked it up on returning from the walk - this probably explains Sparky's barking reaction to the stone - perhaps he could sense its shocking past!

I converted the photograph to B&W too as the atmosphere lends itself to that style, but could not decide which was best - I like them both!
