King Charles III shed a tear as his mother, the Queen, was finally laid to rest after 11 days of mourning.
It was a personal farewell but one as the world watched on to also bid goodbye to Queen Elizabeth II after her incredible 70-year reign.
Buckingham Palace confirmed at 9pm UK time (6am Tuesday, AEST) that the Queen had been buried with the Duke of Edinburgh.
Earlier on Monday, Her Majesty began the short journey from her lying-in-state at Westminster Hall to the Abbey.
Visibly emotional members of the royal family - including Prince William and Harry and King Charles - walked behind the monarch's coffin as it entered the church, with the Princess of Wales and her sister-in-law Meghan putting on a united front.
World leaders, including Australian Prime Minister Anthony Albanese alongside New Zealand Prime Minister Jacinda Ardern, US President Joe Biden and French President Emmanuel Macron, were in attendance.
The Queen’s coffin then travelled to Windsor with thousands of people lining the route through the west London suburbs.
She was moved to the Royal Vault following a short service at St George's Chapel in Windsor Castle.
At 7.30pm (4.30am AEST) a private burial for family members only took place at the chapel. Buckingham Palace called this, final event, a "deeply personal family occasion".
In a statement issued around 9pm UK time (6am Tuesday, AEST) Buckingham Palace confirmed the Queen had been finally laid to rest concluding the various ceremonies following her passing.
"The Queen was buried together with The Duke of Edinburgh, at The King George VI Memorial Chapel," the Palace said.
Shortly before the burial a short ceremony was held behind closed doors for the Royal Family and the Queen's closet aides.
After 11 days of mourning the very last official ceremony to mark the Queen's passing has taken place.
At 7.30pm UK time (4.30am AEST) a burial was held for the late monarch in Windsor.
During that service, the coffin was taken from the Royal Vault directly beneath St George's Chapel.
She was then buried close by at the King George VI memorial chapel, within St George's Chapel, alongside her husband Prince Philip.
This evening a Private Burial will take place in The King George VI Memorial Chapel at Windsor.

Princess Charlotte may be only seven and younger than big brother George but the middle Wales knows a thing or two about etiquette.
In a sweet scene at Hyde Park Corner, as the Queen's coffin was transferred to a car to make its way to Windsor, Charlotte was was standing beside George.
Looking up at George, she seemed to know something wasn't quite right.
She looked at him and appeared to mouth, "you need to bow," reported The Sun.
It seemed as though Charlotte was reminding her brother of royal protocol, and informed him that he needed to bow as the coffin was driven past.
Upon being told of his duty by his younger sister, George – who looked smart in a navy blue suit – nodded.
Charlotte herself has to be consoled after the long and emotional day apparently breaking down in tears at one point.
King Charles III was brought to tears as the coffin of his mother was was lowered into the Royal vault after a short service at St George's' Chapel at Windsor Castle.
It brings to an end the public ceremonies for the Queen's passing.
The coffin of the monarch was shown being lowered into the vault live on television, an historic first.
She will rest alongside her late husband, Prince Philip.
Before the coffin went down, the crown was removed symbolically showing how the power to reign had now moved from her.
Members of the Royal Family were present at the smaller ceremony. But the guest list was far smaller compared to the one earlier at Westminster Abbey.
Charles looked at points exhausted and emotional as he said a final goodbye.
The service was conducted by the Dean of Windsor, with prayers said by the Rector of Sandringham, the Minister of Crathie Kirk and the Chaplain of Windsor Great Park, reportedThe Sun.
Following the penultimate hymn, the imperial state crown, the orb and the sceptre were moved from the Queen's coffin to the altar.
The King then placed the Queen's Company Camp Colour of the Grenadier Guards on the coffin before the Lord Chamberlain broke his Wand of Office.
The Dean said a psalm and the Commendation while the coffin was lowered into the royal vault.
The ceremony came to an end with the singing of God Save the King.
The Royal Family will have a private burial for the Queen, without cameras, at 7.30 pm (UK time), 4.30am AEST.
King, William, Harry watch on as Queen arrives at Windsor
King Charles III, William, Prince of Wales, and Harry, Duke of Sussex, have greeted the Queen as she arrived at Windsor for the final ceremonies before she is laid to rest alongside Prince Philip.
The hearse took two hours to travel from central London to Windsor Castle, along main roads so mourners could watch the procession pass.
Other members of the Royal Family arrived in cars ahead of the hearse.
In a ceremony at St George's Chapel, the family members stood to one side. It is the same chapel where Harry and Meghan wed.
Thousands line route of hearse from London to Windsor
Enormous numbers of people have lined the route of the Queen's final journey from London to Windsor.
The route from Westminster Abbey west through the London suburbs to Windsor deliberately avoided the motorways so mourners could watch the hearse pass by.
Cheers could be heard and flowers were thrown at the hearse as it slowly passed through Kensington, Chiswick, Hounslow and skirted Heathrow airport on its two hour journey to Windsor.
Thousands of people looked on along the Long Walk in Windsor to see the Queen pass by, the final public viewing area before the hearse reached Windsor Castle.
A memorial will be held at St George's Chapel at the castle with a smaller contingent of people.
The global VIPs that came to the Abbey won't be present at Windsor. Instead it will be the Royal Family and members of the royal staff.
The Queen will then be laid to rest alongside her late husband, Prince Philip.
The day's proceedings have proved to be too much for one of the youngest members of the Royal Family attending the funeral.
Heartbreaking images of Princess Charlotte, the Prince and Princess of Wales' daughter, showed her crying during the state funeral for the Queen.
The seven year old was at the funeral with big brother Prince George. For much of the funeral she had remained stoic.
But the tears began to fall as her great grandmother's coffin was lowered into a hearse at Wellington Arch, Hyde Park Corner, for ist final journey to Windsor.
Mum Kate Middleton comforted Charlotte as the tears flowed.
As the Queen's coffin travels on its final journey from Westminster Abbey to Windsor, a remarkable thing is happening in the skies above London.
It is entirely bereft of aeroplanes.
The approach to London Heathrow – one of the world's busiest airports – takes planes right over the CBD. That would mean the Queen's funeral drive, which passes Heathrow, would be accompanied by the sound of roaring engines.
But all aircraft have had to pause operations while the Queen is taken to Windsor to preserve the silence.
Images from flight tracking website FlightRadar 24 shows barely any aircraft over London where usually there would be a conveyor belt of planes from all across the world.
Spare a thought for passengers on Latam flight 8084 from Sao Paulo in Brazil and British Airways flight 108 from Dubai who have had to circle for some time over southern England while waiting for the cortege to pass in serenity.
As soon as the Queen's hearse was out of earshot of the airport, the planes were allowed to land.
