Queenborough Castle is a fourteenth-century fortification constructed on the Isle of Sheppey in Kent under the direction of Edward III, likely designed by the military engineer Henry Yevele. Built between 1361 and 1373, the castle served as a royal stronghold and coastal defence against French attack during the Hundred Years' War, featuring a distinctive concentric plan with a circular keep surrounded by defensive walls. The castle was substantially dismantled in the seventeenth century following the English Civil War, and today only fragmented remains of its foundations and earthworks survive above ground. Its strategic location guarding the Thames estuary made it an important element in England's medieval naval defence network.
