Only in Britain: a museum dedicated to the pencil, with exhibits including a pencil made for the Queen's Diamond Jubilee, wartime spy pencils that were hollowed out for secret maps, and the world's largest pencil (a mighty 8m long). It all stems from the discovery of graphite in the Borrowdale valley during the 17th century, after which Keswick became a major pencil manufacturer.
