The Royal Family's Instagram account paid tribute to the Queen alongside a stunning photo of her walking through the countryside.
In the picture, the Queen is holding a walking stick while wearing a green coat and patterned head scarf.
She was photographed at Balmoral, her residence in Scotland, in 1971, according to Sky News. The photo was taken by Patrick Lichfield, who is the 5th Earl of Lichfield.
"'May flights of Angels sing thee to thy rest.' In loving memory of Her Majesty The Queen. 1926 - 2022," the caption read in reference to Shakespeare's Hamlet.
"To my darling Mama, as you begin your last great journey to join my dear late Papa, I want simply to say this: thank you," he shared at the time. "Thank you for your love and devotion to our family and to the family of nations you have served so diligently all these years."
He concluded the speech with the line from Hamlet which is often used to respect someone who has died, The Evening Standard reports.
The tribute post comes after the Queen was laid to rest beside her husband of 73 years, Prince Philip, during a private burial service following her state funeral on Monday, Buckingham Palace confirmed.
Prince Philip, who died at age 99 in April 2021, was moved from the Royal Vault beneath the chapel, where he was temporarily interred, to be by her side.
