Britain's Queen Elizabeth and Prince Philip observe a minute's silence in the quadrangle of Buckingham Palace, for the Grenfell Tower fire disaster, ahead of the Trooping the Color ceremony in London on June 17, 2017.
The ceremony of Trooping the Color is believed to have first been performed during the reign of King Charles II. In 1748, it was decided that the parade would be used to mark the official birthday of the Sovereign. More than 600 guardsmen and cavalry make up the parade, a celebration of the Sovereign's official birthday, although the Queen's actual birthday is on April 21.
