Princess Diana died 23 years ago on Aug. 31 and her brother, Charles Spencer, did his yearly "family duty" to honor the Princess of Wales.

The Earl Spencer posted, via his social media account, a photo of the family flag at half-mast at their estate is Althorp House. Charles, who is younger than her departed sister, said that this is his very first family duty every Aug. 31. He needs to make sure that Princess Diana is never forgotten. 

Princess Diana's grave is actually found at the Althorp House, in a special man-made island that the Earl Spencer had ordered built for her sister. The estate, located in Northamptonshire, England, belongs to the Spencers for more than 500 years and it is currently where Charles and his family reside. 

In 2017, Charles said, in an interview, with People that Princess Diana was a genius when it comes to connecting with any person. The earl said that Prince William and Prince Harry's mother had a way of putting people at ease and it was one of her incredible gifts

A few days before the anniversary of her death, Prince William and Harry released a joint statement to announce that their mother's statue at Kensington Palace will finally be unveiled on her birthday on July 31, 2021. The royal brothers and a special committee originally planned for this statue to be ready on her 20th death anniversary. 

However, delays on the project, including the COVID-19 pandemic, pushed back the unveiling. Artist Ian Rank-Broadley has been working on the statue since the original plan. 

Meanwhile, CNN reported that tributes to Princess Diana continue to pour every end of August to honor her life and legacy, even after two decades. Prince Charles' ex-wife was dubbed the People's Princess after then-Prime Minister Tony Blair used this title to announce her death to the world. 

Apparently, the title struck a chord after all these years because Princess Diana continues to have a kinship with the public. She is still touching lives through her Diana Foundation.

Her death happened when the royal family had been spending their summer holiday in Balmoral. Prince Charles flew to France to claim Princess Diana's body and left their sons, William and Harry, who were budding teenagers at that time, to their grandparents' care. 

During her funeral, Queen Elizabeth was seen bowing as her daughter-in-law's casket passed in front of her. Royal historian Jane Ridley said that this was the only time that the monarch bowed to anyone.
