The picture of the Queen, wearing a face mask and sat alone at her husband's funeral, was one of the most defining images of the coronavirus pandemic.
Following her death this week, a complex list of royal protocol has been enacted, which includes her funeral arrangements and the final resting places of her and her husband.
Where will the Queen be buried?
On the day of her funeral, the Queen’s coffin will be taken to St George’s Chapel at Windsor Castle for a televised committal service.

Later in the evening, there will be a private interment service with senior members of the royal family.
The Queen’s final resting place will be the King George VI memorial chapel, an annex to the main chapel.
Where is Prince Philip buried and will his coffin be moved?
The Duke of Edinburgh's current resting place is the Royal Vault at St George's Chapel.
However, following the death of the Queen, his coffin will be moved from the Royal Vault to the memorial chapel so their final resting place is together.
The chapel is also where the Queen's mother (Queen Elizabeth The Queen Mother) and father (King George VI) were buried, along with the ashes of her sister, Princess Margaret.
When is the Queen's funeral?
The exact date of the Queen's funeral has yet to be confirmed, but it is likely to be on either 18 or 19 September.
The funeral will take place at Westminster Abbey in London. The original plans are for the Queen’s coffin to process on a gun carriage to the abbey, pulled by naval ratings – sailors – using ropes rather than horses.
Senior members of the family are expected to follow behind – just like they did for the funeral of Diana, Princess of Wales and the Duke of Edinburgh.
The military will line the streets and also join the procession.
Heads of state, prime ministers and presidents, European royals and key figures from public life will be invited to gather in the abbey, which can hold a congregation of 2,000.
The service will be televised, and a national two minutes’ silence is expected to be held.
What will happen before the Queen's funeral?
On Sunday, 11 September, the Queen's coffin is expected to be taken by road from Balmoral to the Palace of Holyroodhouse in Edinburgh.
On Monday, a procession is expected along the Royal Mile to St Giles’s Cathedral, where the public may get the chance to file past the Queen’s coffin at a mini lying in state.
On Tuesday, 13 September, the Queen's coffin is expected to be flown to London, where it is planned to rest at Buckingham Palace.
The Queen's lying in state could begin on Wednesday, 14 September in Westminster Hall, lasting four days.
Hundreds of thousands of people will file past the coffin on its catafalque and pay their respects, just as they did for the Queen Mother’s lying in state in 2002.
Senior royals are also expected to pay their own moving tribute, standing guard at some stage around the coffin – the tradition known as the Vigil of the Princes.
