Dating back to the days of the Norman Conquest, Dover Castle has served as an essential part of England's defences for nearly 1,000 years. From medieval kings to wartime admirals, the castle is ripe with British history.

Make sure you climb the Great Tower, built by Henry II, where lavish tapestries and furniture have been painstakingly recreated to give you an idea of court life in the Middle Ages.

Amid the white cliffs, you'll be able to get a glimpse of the experiences of civilians and commanders during World War II. A range of special effects and documentary recordings will let you relive the events of May 1940, when Admiral Sir Bertram Ramsay orchestrated the rescue of 338,000 troops from Dunkirk during Operation Dynamo.

If you're visiting during summer, you can enjoy a taste of modern military might and see the only working British 3-inch gun in the world being fired. Looking to travel even further back in time? On selected days, the tower is brought to life by costumed interpreters, recreating the court of King Henry II.

A major new attraction, Dover Castle Under Siege, is opening on the 22 July. The attraction will tell the story of the castle's most challenging times through immersive interactive displays and reopened medieval tunnels.
