Just two days before the funeral will take place at St George's Chapel, which is at Windsor Castle, crowds of people gathered on the Long Walk to watch the rehearsals for the big event.

That same day, Buckingham Palace released details about the funeral, revealing that Prince Harry and Prince William will not walk next to each other.
The order was "a practical change rather than sending a signal," a Buckingham Palace spokesman revealed. "This is a funeral and we are not going to be drawn into perceptions of drama. The arrangements have been agreed and represent Her Majesty's wishes."
Even though the Palace has encouraged people to stay home amid the pandemic, a crowd gathered to watch the mounted military on their horses.
The mounted military approached the Long Walk and practiced before Saturday's event.
Armed police rehearsed for the Duke's funeral, which will begin at 3 p.m. U.K. time (10 a.m. EST time) on Saturday.
The couple's four children — Prince Charles, Princess Anne, Prince Andrew and Prince Edward — will be there, along with Charles' wife, Camilla, Duchess of Cornwall, Anne's husband, Timothy Laurence, and Edward's wife Sophie, Countess of Wessex.
Philip's eight grandchildren — Peter Phillips, Zara Tindall, Prince William, Prince Harry, Princess Beatrice, Princess Eugenie, Lady Louise and James, Viscount Severn — will also be there.
