Dover Castle

Dover Castle is the medieval castle on the white cliffs above the Channel at Dover, Kent, in the care of English Heritage, with Henry II's Great Tower and the Secret Wartime Tunnels.

Why go

Dover Castle is cared for by English Heritage, whose pages describe Henry II's Great Tower at the heart of the castle, the Secret Wartime Tunnels including the Underground Hospital, and an exhibition on the siege of 1216-17. English Heritage's prices page says tickets are sold by timed slot, that visitors can stay as long as they like within opening hours, and that tickets can be booked online until midnight the day before or bought on the day online or on arrival. English Heritage posts updates on which parts of the tunnels are open, so check its page before you go. This record is the castle in Dover; Canterbury is a travel base for it, not its location, and its map point is inside the castle grounds, not an entrance.
