NEW YORK, N.Y. - Queen Elizabeth II and her husband, Prince Philip, the Duke of Edinburgh, will spend Tuesday afternoon in Manhattan, following a nine-day tour of Canada, before flying home to Great Britain in the evening.
Tuesday's visit marks the 84-year-old monarch's third trip to New York City more than four decades after her first visit in 1957 and second in 1976.
The Queen will begin with an address to the United Nations General Assembly, where she will take "a global perspective," Harriet Cross, speaking on behalf of the United Kingdom's Mission to the United Nations, said.
"She will touch on progress made since she was last here and [the] challenges that remain," Cross said.
In late afternoon, the Queen and Prince Philip will visit Ground Zero, where they will be met by an honor guard, New York Mayor Michael Bloomberg and Gov. David Paterson, and New Jersey Gov. Christopher Christie.
After a tour of the 16-acre site where thousands perished, the royal couple will travel cross town to the British Garden in Lower Manhattan's Hanover Square. Here they will visit the memorial honoring the 50 British citizens who died in the September 11 bombing of the World Trade Center.
Relatives of the victims will be on hand to meet the Queen and her husband and participate in a ribbon-cutting ceremony to officially open the memorial garden.
The mayor and governor of New York, the governor of New Jersey, along with British Ambassador to the U.S. Sir Nigel Elton Sheinwald, New York Consul General Sir Alan Collins and the leaders of the British Memorial Garden Trust will escort Queen Elizabeth and Prince Philip on a walk through the site.
