Just too add a wee note...if you travel up Rochester Road out of Aylesford, cross under the A249 and continue straight on, take the first turning left, the immediate ground to the left is scattered with sarsens as you climb up quite a steep, overgrown road. These could be natural or man-placed, but being in pretty dense woodland doesn't help to make sense of anything. Also, along Gleaming Wood Drive, less than a mile away towards Horsted, the road is lined with local cleared sarsens.

Then of course, there's the name Capstone Park in the same area....
