King Charles III led the procession of the coffin from Buckingham Palace to the Houses of Parliament for her lying in state.
From the dust and dirt of a warzone to the gleaming uniforms of an army parade -- these are the images that show the reality of life for British servicemen and women. The revealing series of photographs are some of the winning entries in this year's Army Photographic Competition.
Prior to the state funeral, the late British monarch will lie-in-state at Westminster Hall nearby for four days to allow the public to pay their respects.
"Over the last 10 days, my wife and I have been so deeply touched by the many messages of condolence and support we have received from this country and across the world," Charles said in a statement
"God save the King" were the words with which those gathered reaffirmed the proclamation made by the clerk of the council.
Members of the public began filing past at 5pm local time and will have until 6.30am on the day of the funeral, by which time several thousands are expected to have queued for hours to pay their respects to the Queen.
The funeral incorporated hymns and readings chosen by the late royal himself and focussed on the "unwavering loyalty" of the longest-serving consort in British history to his wife, the monarch, and service to Britain and the Commonwealth.
Churches also tolled their bells, after the Church of England sent out guidance to parishes, chapels and cathedrals across the country encouraging them to open for prayer or special services. Major sporting events, including football and cricket matches, have been postponed as a mark of respect.
The state funeral on Monday will take the form of an elaborate ceremony that will see Her Majesty's coffin transported from Westminster Hall to Westminster Abbey and finally to Windsor Castle.
