A memorial garden, for President John F Kennedy. The acre of land on which it is set, a gift to America, overlooks the valley in which Magna Carta was signed. Jellicoe designed a flight of steps, rising through the woods to reach a glade in which the memorial stone is set. It draws upon The Pilgrim's Progress, Bunyan's allegory of life as a journey. This was a key project in the development of Jellicoe's view on the role of the subconscious in landscape design.
