John F. Kennedy Memorial
JFK Memorial designed by Geoffrey Jellico The British memorial to the assassinated President Kennedy was jointly dedicated in May, 1965, by Queen Elizabeth II and Jacqueline Kennedy, prior to a reception for the Kennedy family at Windsor Castle. The memorial consists of a Portland stone memorial tablet inscribed with the famous quote from his Inaugural Address:
"Let every Nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend or oppose any foe, in order to assure the survival and success of liberty".
Visitors reach the memorial by treading a steep path of irregular granite steps, intended to symbolise a pilgrimage. The area of ground that the memorial is situated on was given as a gift to the United States of America by the People of Britain, and as such it is American territory. (It is an extraterritorial site in roughly the same sort of way that an embassy is considered to be. A similar situation exists in Hawaii, where the spot on which James Cook died has been given to Britain.) It is maintained by the Kennedy Memorial Trust, which also sponsors educational scholarships for British students to attend university in the United States.
