The Queen will be buried alongside her beloved husband Prince Philip in the Royal Vault at Windsor, it has been confirmed by Buckingham Palace.
She will be laid to rest in a private service in King George VI's chapel following her state funeral on Monday morning.
King Charles III and other key members of the Royal Family will walk behind her coffin to Wellington Arch when it leaves Westminster Abbey after the funeral.
A committal service will then take place at the chapel on the Berkshire estate - around 20 miles from Westminster - at 4pm.
Prior to the funeral, the new monarch and his siblings, Princess Anne and Princes Andrew and Edward, will mount a 15-minute vigil around their mother's coffin as it lies in state at 7.30pm on Friday.
The Duke of York has been given special permission by Charles to don a military uniform.
This is despite being stripped of his honorary titles and stepping down as a working royal after the Jeffrey Epstein and Virginia Giuffre scandals.
Elizabeth II's funeral is due to begin at 11am and be broadcast to millions of people across the world.

Strict protocol has been issued to those invited, with around 500 heads of state, royals and other political luminaries likely to attend.
While almost 200 everyday heroes are also on the guest list.
The overall numbers could surpass the 2,000 that were present for Princess Diana's funeral and the 3,500 that accepted invites for Winston Churchill's final farewell.
And while her children and grandchildren are all involved, as well as their partners, it is not yet known if her great-grandchildren will attend.
Her Majesty's coffin arrived at Westminster Hall on Wednesday afternoon and will lie in state there for four days, with more than a million people forecasted to file past.
William and Harry could walk side-by-side behind their grandmother's coffin on Monday.
The funeral is breaking hundreds of years of royal tradition as it will be the first time such a service will be held at the abbey for a British monarch.
George II's funeral in 1760 was the last time it happened.
Funerals for the country's kings and queens have normally been held 20 miles away at St George's Chapel, though that is where she'll be buried.
She will be laid to rest next to her late husband as well as her sister Princess Margaret and parents King George VI and Queen Elizabeth The Queen Mother.
The funeral has been officially declared a Bank Holiday for the UK, meaning many people could have the day off work.
The public service will “unite people across the globe and resonate with people of all faiths” and pay a “fitting tribute to an extraordinary reign”, the man in charge of the historic occasion has said.
The Earl Marshal, the Duke of Norfolk, described the task as “both humbling and daunting. An honour and a great responsibility”.
Some 800 people, including members of the Queen’s Household and Windsor estate staff, will attend the committal service afterwards at Windsor.
Among those invited to the funeral are almost 200 people who were recognised in Queen’s Birthday honours for extraordinary contributions including response to Covid.
Including Charity workers, healthcare, education, public sector, community volunteers.
The burial service, conducted by the Dean of Windsor and attended by the King and royals, will remain entirely private, as a “deeply personal family occasion”.
The earl said: “The events of recent days are a reminder of the strength of our Constitution, a system of government, which in so many ways is the envy of the world.
“The Queen held a unique and timeless position in all our lives. This has been felt more keenly over the past few days as the world comes to terms with her demise.
“Her Majesty’s passing has left many people across many continents with a profound sense of loss.
“The respect, admiration and affection in which the Queen was held make our task both humbling and daunting. An honour and a great responsibility.
“It is our aim and belief that the state funeral and events of the next few days will unite people across the globe and resonate with people of all faiths, whilst fulfilling Her Majesty and her family’s wishes to pay a fitting tribute to an extraordinary reign.”

The King will once again lead his family in marching behind the Queen’s coffin when it is moved, at 10.44am on Monday, from Westminster Hall to Westminster Abbey for the Queen’s funeral service.
He will walk with the Princess Royal, Duke of York and Earl of Wessex and behind the quartet will be the Queen’s grandsons Peter Phillips, Duke of Sussex and the Prince of Wales.
They will be followed by the late monarch’s son-in-law Vice Admiral Sir Tim Laurence, the Duke of Gloucester, the Queen’s cousin, and her nephew the Earl of Snowdon.
The Queen’s coffin will be carried during the procession on a 123-year-old gun carriage towed by 98 Royal Navy sailors in a tradition dating back to the funeral of Queen Victoria.
The Procession will be led by a massed Pipes & Drums of Scottish and Irish Regiments, the Brigade of Gurkhas, and the Royal Air Force – numbering 200 musicians.
At 8am the doors of Westminster Abbey will open for the congregation to begin taking their seats.
Heads of state and overseas government representatives, including foreign royal families, governors general and Realm prime ministers, will gather at the Royal Hospital Chelsea and “travel under collective arrangements” to the Abbey, the Earl Marshal said.
He added that other representatives of the Realms and the Commonwealth, the Orders of Chivalry including recipients of the Victoria Cross and George Cross, Government, Parliament, devolved Parliaments and Assemblies, the Church, and Her Majesty’s Patronages will form the congregation, along with further representatives from law, emergency services, public servants and professions, and public representatives.
Members of the British royal family who are not processing from Westminster Hall will have arrived at the abbey and been escorted to their seats in the South Lantern.
The procession will arrive at the west gate of Westminster Abbey at 10.52am when the bearer party will lift the coffin from the gun carriage and carry it into the Abbey for the state funeral service, the Earl Marshal said.
The service will begin at 11am and will be conducted by the Dean of Westminster.
The Prime Minister and the Secretary General of the Commonwealth will read Lessons, while the Archbishop of York, the Cardinal Archbishop of Westminster, the Moderator of the General Assembly of the Church of Scotland and the Free Churches Moderator will say prayers.
The sermon will be given by the Archbishop of Canterbury who will also give the commendation, while the Dean will pronounce the blessing.
At around 11.55am the Last Post will sound, followed by two minutes of silence to be observed in the Abbey and throughout the UK.
Reveille, the national anthem and a lament played by the Queen’s piper will bring the state funeral service to an end at around 12 noon.
The bearer party will then lift the coffin from the catafalque and will move in procession through the Great West Door returning to the State Gun Carriage positioned outside the West Gate.
The coffin will be followed by the King and the Queen Consort, the Prince and Princess of Wales and members of the royal family who will walk in the procession to Wellington Arch.
