King Gives Sunninghill To Princess Elizabeth And Lt. Phillip Mountbatten -- Frontal view of Sunninghill, Park, situated between Windsor great park and the ascot race course. It was announced in London (England) last week that HM king George VI "has been graciously pleased to grant Sunninghill Park to princess Elizabeth as a grace and favor residence". This means that Sunninghill, situated between Windsor great Park and the ascot racecourse, will be the country home of the Royal couple after their wedding. The house is not yet suitable for occupation having been used by the Royal air force until recently. Only a few rooms will be redecorated for use of the princess and Lieut. Mountbatten.
