And in a touching tribute, Prince Willliam, Prince Harry, and Kate Middleton re-dedicated her grave at Diana's resting place at her family home, Althorp House, in Northamptonshire, England.
Kensington Palace previously confirmed the ceremony. "The service, which will fall on what would have been the Princess's birthday, will be conducted by The Archbishop of Canterbury, and attended by her family," a statement from the Palace explained.

According to BBC News, Diana's sons were joined by Kate, William and Kate's kids, Prince George and Princess Charlotte, and the Princess of Wales' brother, Earl Charles Spencer. The re-dedication ceremony involved prayers, readings, and an address from a minister — in this case, The Archbishop of Canterbury. Prince Charles, her ex-husband, was noticeably absent from the event.
Following the 36-year-old's public funeral in London on Sept. 6, 1997, the princess was taken back to a private island on the grounds of Althorp Park, which Charles Spencer resides in. At the time, Diana's brother explained it would be her final hope for peace in a secluded location away from the world's prying eyes.
In 2014, Diana's former chef Darren McGrady took to social media exposing photos of the overgrown burial site covered in moss. "Sad to see Earl Spencer has neglected Diana's resting place. Please tidy up the vegetation on the island," he said at the time.
However, a spokesperson for Althorp hit back at the claims saying that the overgrown nature of the grave was "part of the ancient landscape over time" and said they had left it that way to "lend privacy to the Princess's final resting place." Since then, it has undergone refurbishments.
Now more than ever, Prince William and Prince Harry have opened up about their immeasurable loss. Most recently, Harry slammed the palace's decision to let him walk behind Diana's coffin at her funeral.

"My mother had just died, and I had to walk a long way behind her coffin, surrounded by thousands of people watching me while millions more did on television," he told Newsweek. "I don’t think any child should be asked to do that, under any circumstances."
William similarly admitted to GQ how much it pains him that Diana isn't around to meet his wife and children. "I would like to have had her advice. I would love her to have met Catherine and to have seen the children grow up. It makes me sad that she won’t, that they will never know her," he said.
