The coffin carrying Queen Elizabeth II left Buckingham Palace on Wednesday to make the short, sombre journey to Westminster Hall in central London, where it will lie in state for four full days until her funeral on Monday.
The coffin departed the palace for Westminster Hall carried on an open gun carriage of the King's Troop Royal Horse Artillery, drawn by a team of black horses.
Huge crowds assembled along the route, with people hoping to get a glimpse of the Queen's coffin and King Charles III, who followed behind on foot with other senior royals.
Guns were fired at one-minute intervals throughout the procession from Hyde Park, where people watched the event on large screens.
Some 1,000 members of the armed forces took part in events surrounding the parade. Captain Amy Cooper led the procession on a huge 18 hands-tall (183cm) veteran horse named Lord Firebrand.
The gathered crowds fell silent as the procession reached the Palace of Westminster - the home of the UK Parliament.
King Charles III and the other members of the Royal Family saluted as the bearer party carried the Queen's coffin into Westminster Hall.
