Dover Castle

The English Heritage site of Dover Castle, one of the most popular places to visit in the country, is an easy castle to visit from London. Dover Castle is often referred to as the “Key to England” because of its important location: the castle is perched above the English Channel and has acted as the first line of defense during medieval battles and modern wars.

Dover was originally built in the 1180s by King Henry II. However, throughout history, the castle continued to be developed and adapted to meet the needs of the time. Used in many battles and wars, including World War II, the history of Dover Castle is very diverse.

Although the castle is no longer in military use today, various portions of the structure have been preserved to give visitors an idea of what it would have felt like to be in the castle during a war. This immersive experience is one of the things that makes Dover Castle worth visiting.

Dover Castle Tunnels

Dover Castle’s medieval tunnels are one of the most popular attractions of the site. These underground tunnels span nearly three miles across five different levels – some of which haven’t even been fully restored yet! In order to see the tunnels, you’ll need to participate in a tour of Dover Castle, where you can learn about the significance of these underground passages.

The tunnels of Dover Castle played a major role in the defense of England during World War II, particularly during Operation Dynamo (also known as Operation Dunkirk), which was designed to protect the English Channel from invasion.

Today, segments of the Dover Castle tunnels that were used during WWII have been decorated to look as they would have during the war. Guests can walk through hospital rooms where wounded soldiers were treated and combat planning studies where leaders made important decisions.

Other parts of the tunnels have been preserved from medieval times to give you an appreciation for the age and impressive architecture of the building.

Facts about Dover Castle

The outer walls of Dover Castle encompass an area of approximately 30 acres, making it England’s largest castle (Windsor Castle is the largest inhabited castle).

Dover was never intended as a place of residence. The location on the English Channel is a strategic one, and it was designed to be a fortress that could protect the rest of England.

Not only is Dover Castle itself magnificent, but the surrounding area is one of the most spectacular spots in England. The white cliffs of Dover are one of the most famous natural attractions of England, which stretch along the shoreline near the castle.
