Walmer Castle

Henry VIII's government built it in 1539–40 as an artillery fort, with a central keep and four rounded bastions inside a moat.

For nearly three centuries it has been the official residence of the Lord Warden of the Cinque Ports, a post held by William Pitt the Younger, the Duke of Wellington, Winston Churchill and the Queen Mother.

The gardens have flower-filled borders, a kitchen garden, wildflower meadows, woodland walks and a yew cloud hedge on the Broadwalk.
