Perched high on the White Cliffs, Dover Castle watches the English Channel at its narrowest point—hence its proud nickname, the “Key to England.” From a Roman lighthouse to medieval battlements and secret war tunnels, the site layers two millennia of defense into one dramatic headland. Come for sweeping sea views; stay for stories that stretch from knights to code names.

Historical Context
Dover’s headland has been fortified since the Iron Age, but its story leaps to life with a 1st‑century Roman lighthouse and the nearby Saxon church of St Mary in Castro. After 1066, William the Conqueror raised a motte-and-bailey here; a century later, Henry II turned the site into a powerful stone fortress-palace crowned by the Great Tower. In 1216, the castle withstood a fierce siege by Prince Louis of France. Its defenses evolved with gunpowder, and deep tunnels were dug in the 18th–19th centuries. In 1940, Admiral Bertram Ramsay directed the Dunkirk evacuation from these tunnels, later adapted as a hospital and, in the Cold War, a government bunker.
