A legend, relevant to this part of the house, is that King Edward III and the Black Prince stayed at Hampden House. During the stay the prince and his Hampden host were jousting, when a quarrel arose, during which the prince was punched in the face by his host. This act of "lèse majesté" caused the king and Prince to quit the place in great wrath, and cause their host to forfeit some of his estates to the crown. There is, however no documentary evidence for this act, or of the subsequent revenge although the Black Prince is known to have possessed land in nearby Princes Risborough during his life.
