Not the White Cliffs of Dover, but the Seven Sisters (if you count the hills), which are in East Sussex between Eastbourne and Seaford, off the A259. We walked the length of them, up down up down, on a walking holiday in July 2009. A very pleasant day, one of a week's 10km-or-so daily excursions. (We kept to the 'easy walk' category; there were also medium and difficult ones to chose from day to day.)
We came across this knotty tree on another, rural walk in Sussex. It wasn't far from a small Norman church but I can't remember the exact location.
The Chanctonbury Ring, ancient fortress and temple, sown in later times with beech trees. Local legend has it that the Chanctonbury Ring was created by the Devil and that he can be summoned by running around the clump of trees seven times anti-clockwise. When he appears he will offer you a bowl of soup in exchange for your soul. Obviously not a consomme or any kind of clear soup. Have to be a murky broth, it would!
