LONDON — 

Queen Elizabeth II is marking her 96th birthday privately Thursday, retreating to the Sandringham estate in eastern England that has offered Britain’s longest-reigning monarch and her late husband, Prince Philip, a refuge from the affairs of state.

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.”

This birthday comes during the queen’s platinum jubilee year, marking 70 years on the throne. While Thursday’s will be low-key, public celebrations will take place June 2-5, when four days of jubilee festivities have been scheduled to coincide with the monarch’s official birthday.

The day marks yet another milestone during a tumultuous period for Elizabeth, who has sought to cement the future of the monarchy amid signs of her age and controversy in the family. After her recovery from a bout of COVID-19 earlier this year, the queen’s public appearances have been limited by unspecified “mobility issues.”

The legal settlement by her second son, Prince Andrew, with a woman who accused him of sexual exploitation also caused unwanted headlines for the royal family.

But the queen got an early birthday treat last week, when grandson Prince Harry and his wife, Meghan, the Duchess of Sussex, paid her a joint visit for the first time since they stepped away from front-line royal duties and moved to California in 2020. Harry, in an interview with NBC, said his grandmother was “on great form,” though he added that he wanted to make sure she was “protected” and had “the right people around her.”

Elizabeth has spent much of the last two years at Windsor Castle, west of London, where she took refuge during the pandemic.

Prince Philip, her husband of more than 70 years, died slightly more than a year ago. The queen said goodbye to him during a scaled-down funeral in St. George’s Chapel at the castle. Coronavirus restrictions in place at the time limited the service to 30 mourners and forced the monarch to sit alone — a poignant reminder of how she would spend her remaining years.

Last month, with the pandemic on the wane and restrictions eased, the queen shrugged off recent health issues to attend a service of thanksgiving for Philip at Westminster Abbey, entering the church on Andrew’s arm.
