As Queen Elizabeth II lies in state in Westminster Hall, thousands of mourners have been lining up all night to pay their respects.
Princes William and Harry, together with King Charles III, followed the coffin as it was carried from Buckingham Palace.
In the solemn ceremony, guns were fired in Hyde Park, and Big Ben chimed every minute.
People are lined up in over three-mile-long lines along the South Bank of the River Thames to observe the coffin.
In the upcoming days, hundreds of thousands of people are anticipated to arrive.
The funeral for the Queen will take place on Monday, September 19, a holiday.
