In 1216 Dover Castle was besieged by Prince Louis of France. King John left Hubert de Burgh in charge at Dover and even though the French managed to breach the defences by undermining the north gate, de Burgh's forces beat back the attack and Prince Louis called a truce. The truce was short lived as John died soon after and Louis again attempted to take the castle. Louis was eventually defeated by Hubert de Burgh.

Hubert de Burgh with Henry III's backing rebuilt the damaged castle removing areas of weakness that had been exposed during the siege. Of interest now are the newly opened 'Secret War Tunnels' dug into the White cliffs of Dover that were used during World War II as a hospital and for strategic planning.

The keep at Dover Castle is shaped almost like a cube. It is approximately 98 ft by 96 ft and 95 ft high. The turrets are an extra 12 ft higher. Openings in the walls of the gallery allow extra to light into the main hall.

The upper floor of the keep consists of a gallery 1 that runs around the top of the main halls. A break in the gallery forms a couple of rooms 2 containing toilets. Doors lead of the gallery onto the roof of the forebuilding 3.

This plan shows the main floor of the keep. The stairs in the forebuilding end at this level in the area indicated by 4. The main chapel is located on this floor and consists of two rooms in the forebuilding. The keep has two main halls divided by a centre wall 5. Main state rooms surround the two halls that would have been used as living and sleeping quarters for the most important owners and guests. Access to the rest of the castle is via two sprial staircases in the north and south corners of the building 6.

Stairs lead through the forebuilding 7 turning infront of the lower chapel and heading up to the second floor. Rooms on the rest of this floor can only be reached via the spiral staircases in the corners of the building.

The ground floor has a plinth (not shown on the diagram) to prevent battering rams damaging the walls. There is no entrance to the castle on the ground floor. The entrance to the castle is through the forebuilding on the first floor. The ground floor of the keep would have been used for storage of supplies.
