The King Stone which stands apart from the main circle and "Whispering Knights" at Rollright, Oxfordshire.
Perhaps memorial to a great battle success of Danish King Rollo, perhaps a moot spot...
In recent folklore Faerie folk are said to live beneath the circle, in great caverns, some of which are linked up to the single monolith across the road. Ravenhill  described how local folk had sometimes seen the little people dancing around the circle by moonlight, but nobody has seen them of late.
Whatever the truth, I do like a good oolitic limestone megalithic complex...
