The message included, “Then, in 1928, it was never expected she would be Queen, and this year Her Majesty is celebrating her #PlatinumJubilee – a first in British history,” referencing her celebrating 70 years on the throne in June.

Prince Charles and Camilla added:

The Band of the Coldstream Guards also played “Happy Birthday” for the Queen at Windsor Castle, while a 41-gun salute celebrated the special occasion by the King’s Troop, Royal Horse Artillery, in Hyde Park, close to Buckingham Palace.

Royal Gun Salutes have been fired at saluting stations in key locations across England, Scotland, Wales and Northern Ireland, as well.

The Queen is spending her birthday at her Sandringham Estate in Norfolk, U.K.

A senior Buckingham Palace spokesperson said in a statement to E! News: “Her Majesty has travelled to the Sandringham estate for a private break.”

Elizabeth is expected to spend the day at the estate’s Wood Farm cottage, a personal sanctuary where she also spent her first Christmas since Philip’s death in April 2021. Philip loved the cottage, in part because it is close to the sea, she said in February when hosting a rare public event at Sandringham.

“I think the Queen’s approach to birthdays very much embodies her ‘keep calm and carry on’ attitude,” said Emily Nash, the royal editor at Hello! magazine. ”She doesn’t like a fuss.”

The Queen has increasingly relied on Prince Charles to take on public engagements in the twilight of her reign, most recently offering alms to senior citizens at the Royal Maundy service at St. George’s Chapel.

Charles took on the traditional task of distributing specially minted coins to retirees who were being recognized for service to the church and the local community.

This year, 96 men and 96 women received the coins, one for each year of the queen’s life.

“She has a lot coming up in the next few months, so it absolutely makes sense that she enjoys her birthday quietly, privately at Sandringham,″ Nash said. “She will no doubt have quite a lot of time to reflect on her happy times there with Prince Philip over the years. But this is really someone whose focus is still on the future, even at the age of 96.”
