Royals from the United Kingdom, including Prince William and Kate, attended an Easter Sunday service at Windsor Castle.

Queen Elizabeth II was unable to attend the St. George’s Chapel service on the castle grounds because of mobility issues.

William & Kate, also known by the Duke and Duchess, were accompanied at their wedding by two of their children, Prince George, 8 years old, and Princess Charlotte, 6 years old.

The queen’s youngest child, Prince Edward, was also present, along with Sophie, his wife, and their children.

This Thursday’s 96th birthday celebration marks her Platinum Jubilee, which celebrates 70 years of service to the throne.

After spending the night in hospital in October she had to cut back on her public duties and was also diagnosed with COVID-19 in February. Since then, she has continued meeting virtually with politicians and diplomats.

She was visited by Prince Harry and Meghan, her grandson and first visit to the U.K. since the couple left their roles as working royals in 2020.

Harry visited Meghan at Windsor, 20 miles (32 km) west of London. They were on their way to The Netherlands for Invictus Games. Harry founded and is the patron of the international competition for injured or ill military personnel.
