"Walton Castle now lies in ruins under the sea off Felixstowe, and for its features we must rely on various old descriptions, which give the landward wall variously as 100 or 187 yards long, and 12 or 9 feet thick. A seventeenth-century drawing shows cylindrical bastions at the corners." (Collingwood, p.51)
