Incredible Neolithic flint mines dating from over 4,000 years ago. Owned by English Heritage
Visitors can don a hard hat and descend into one of the shafts to see the radiating galleries at the bottom and the marks made by the antler picks of the original miners.
Try to catch one of the flint-knapping demonstrations (with the knapper in costume wearing only animal skins!).
