The couple rode in an open-topped State Laundau, a carriage built in 1902, to Buckingham Palace.

Massive crowds of onlookers gathered in hopes to catch a glimpse of the royal couple on their big day, as the U.K. observes a national holiday because of the wedding. The London Stock Exchange is closed.

Thousands of people swarmed Trafalgar Square and Hyde Park to watch the live broadcast of the ceremony on huge television screens.

For those who could not be in England to watch the event, coverage was available from a number of television outlets and online, starting as early as 1 a.m. EDT. Coverage is expected to continue for hours following the ceremony.

The palace will hold two parties following the official ceremony. The first celebration for 650 guests is to be hosted by Queen Elizabeth II and Prince Philip, who have been married for 64 years. The queen and her husband will then leave for the evening, and the younger royals will partake in an evening dinner dance.

The total cost of the opulent affair remains unknown, but estimates range from $16 million to $64 million. Reports claim that security accounts for a large portion of the expenses.

The two receptions will cost an estimated $600,000, including $80,000 for two wedding cakes, Amy Eisinger, editor of weddingchannel.com, told
