The term ONE OF THE OLD CINQUE PORTS IN SUSSEX can be solved by the three-letter word RYE. RYE is a small town in East Sussex, England, and one of the original Cinque Ports. The Cinque Ports were a confederation of five coastal towns in the Middle Ages that had special privileges granted to them by the King of England. RYE was one of the five original members of the Cinque Ports, along with Hastings, Romney, Hythe, and Dover.
