The Queen will be buried alongside her beloved late husband Prince Philip in the King George Vl memorial chapel at Windsor Castle.
Their remains will be interred in the small chapel where the Queen's parents are also buried and her sister Margaret's ashes were brought there following her death in 2002.
The Duke of Edinburgh's coffin will be transferred to rest by her side after he was originally placed on a marble slab in the Royal Vault beneath St George's Chapel at Windsor Castle.
Queen Elizabeth's husband passed away back in April 2021 at the age of 99.
George VI died in 1952 but was first interred in the Royal Vault and transferred to the memorial chapel 17 years later, in 1969.
His coffin remains covered by the royal standard that was used at his funeral.
The Royal Vault was created between 1804 and 1810 for George III, who died in 1820, and other kings, like George IV and William IV, have also been buried in the vault.
The Duke of Edinburgh's mother, Princess Alice of Battenberg, was also laid there from her death in 1969 until her burial in Jerusalem in 1988, the Express reported.
The Queen's death has put into place a major operation leading up to her funeral, with members of the Royal Navy understood to have already been told to prepare to carry her coffin.
Elizabeth died on Thursday afternoon at Balmoral, with her eldest son now becoming King Charles III and his wife Camilla the Queen Consort.
It is believed the Queen's state funeral will take place on Monday, September 19, at Westminster Abbey with her coffin lying in state for a number of days beforehand.
As part of the Operation London Bridge plan, the Queen's coffin is expected to process on a gun carriage to the abbey, pulled by sailors using ropes rather than horses.
Members of the Royal Family are expected to follow behind the coffin, with the military lining the streets and also joining in the procession. The service will be televised, and a national two minutes' silence is expected to be held.
