According royal reporter Omid Scobie, Harry arranged for a bunch of flowers to be laid at Althorp House on Sunday, March 14.
The location is where Diana was buried in 1997, just outside of Northampton.
A green clad landscape with beautiful sprawling greens, it's a wonderful peaceful spot to mark Diana's final resting place.
The Cambridge's, who are now back in London, also shared a beautiful gesture for Princess Diana on Mothering Sunday.
Kensington Palace shared three beautiful drawings and messages from Prince George, seven, Princess Charlotte, five, and Prince Louis, two.
In George's note, he wrote: "I love you very much and think of you always."
Charlotte added a beautiful note at the end of her letter: "Papa is missing you."
The Palace also shared another post featuring a delicious looking cake made by the three children for their own mother, Duchess Catherine.
In a second image, Kate and her mother Carole are seen in an image from the Duchess's childhood.
Of course while the topic of Harry and Meghan's explosive Oprah Interview remains a talking point, celebrating our mother's - near, far, here and no longer with us - is always, always something to take time and stop for.
