When was Dover Castle built?
Dover Castle began life as a motte-and-bailey fortress in the 11th century. Built under the instruction of William the Conqueror, it served to protect the narrowest point of the English Channel while acting as a show of power to any would-be invaders.
Subsequent rulers rebuilt, fortified and modified the castle and its surrounds until it became the formidable fortress it is today.
Dover Castle tunnels
Following the castle’s great siege of 1216, Hubert de Burgh, a loyal supporter of King John, built an impressive network of tunnels under the fortress, allowing troops to intercept enemies to the north before they even made it to the main gate.
In Napoleonic times, when the threat of invasion was always present, the tunnels were expanded and used as a barracks. Yet it was during the Second World War that the catacombs would play their most important role in history. The tunnels were expanded to incorporate a secret hospital and an allied base of operations. From here, Winston Churchill led Operation Dynamo, the evacuation of over 300,00 soldiers from Dunkirk.
