English: Entrance to Walmer Castle. Official residence of the Lord Warden of the Cinque Ports (currently Admiral Lord Boyce). This is the main entrance into the North Bastion and would originally have been protected by a short drawbridge, now replaced with a brick bridge. The castle was built in the 16th century for Henry VIII, and forms part of a line of defence along the edge of the Downs. It has a low profile similar in design to nearby Deal castle. Gunpowder was becoming more widely used and high walls would only have provided a greater target area for attack. With low outer walls, reinforced with solid bastions, and the added protection of earth ramparts and moats, there was less of a target for enemy fire but plenty of strength to withstand a battering.
