Twenty years after her death, Princes William and Harry are finding a new way to honor the beloved Princess Diana. The royals have commissioned two documentaries to mark the 20th anniversary of their mother’s death.

William and Harry have asked the BBC and ITV to create the specials, in which they’ll open up about their recollections of their mother’s passing in a car crash in Paris in 1997 when they were just 15 and 12 years old, respectively. The princes will also speak of their memories of the public’s reaction, and have asked others to open up as well.

“The Duke and Prince Harry have selected close friends and family members to speak about Diana, and some will be speaking publicly for the first time,” a royal source told The Sunday Times.

The ITV documentary, set for July, will focus on Diana’s humanitarian legacy, while the BBC’s special, set for August, will look at the nation’s shock and grief following the tragedy. While the royals long stayed quiet about their loss, Princes William and Harry, who work to reduce the stigma surrounding mental health, have recently opened up about how losing their mother affected them.

“I never really dealt with what had happened. There was a lot of buried grief. So for a huge part of my life, I just didn’t even want to think about it,” Harry said in a recent ITV special.
