Deal Castle

Deal Castle stands on the Kent coast, a stone artillery fort built between 1539 and 1540 by Henry VIII. It sits beside the Downs anchorage, a sheltered stretch of water where ships once anchored safely off Deal Beach. The castle covers just over a third of a hectare and was designed with a central keep surrounded by six bastions. Sixty-six gun positions allowed it to fire in every direction. Three similar forts—Deal, Sandown and Walmer—were built close together and linked by earthworks. The fort was part of Henry’s Device programme to guard England against invasion. The original threat from France and the Holy Roman Empire faded, but the castle saw action again in the 1640s. During the Second English Civil War, Royalist supporters took control of Deal and nearby Walmer. Parliament’s forces besieged the castle for weeks before retaking it in July 1648. Later, in the Second World War, German bombing destroyed the captain’s quarters and the castle became an observation post. Inside, visitors find a circular keep with six low bastions radiating outward. The thick walls and moat remain largely as they were in the 16th century. The ground floor rooms were once used for storage and garrison life. Above, the upper levels offer views across the Downs and the English Channel. The surrounding earthworks and nearby bulwarks add to the sense of a fortified coastline. The castle now belongs to English Heritage and welcomes visitors when not in use by the captain.
