Reopened after being badly damaged in the 2015 floods, Keswick's oddest museum is devoted to the charms of the humble 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.

　　You can buy luxury Derwent colouring pencils from the museum shop.
