An imposing fortress looming above the famous White Cliffs of Dover, Dover Castle is not only one of England’s largest and oldest medieval castles, but one of its most strategically important, standing guard over the narrowest point of the English Channel and the first line of defense against mainland Europe.
Although built by William the Conqueror in 1066, Dover Castle actually has a much longer legacy, preceded by an Anglo-Saxon fort and a Roman lighthouse, and seeing battle several times throughout its reign. Visitors can climb the 12th-century Great Tower, walk the battlements, view the ruins of the ancient Roman lighthouse, and even explore the warren of secret wartime tunnels that burrow beneath the castle. There’s also the Princess of Wales' Royal Regiment Museum and a series of exhibitions, where you’ll discover life in the royal court of King Henry II, learn about how the castle was used as a hospital during WWII and relive the horrors of the Siege of 1216.
Dover Castle is located by the port of Dover on the southeast coast of England and is open daily, from April-Oct and weekends only from Nov-March. Opening times vary throughout the year and adult admission at the time of writing is £18.
