So often do William and Harry visit Diana's grave

Diana has never really been gone, but through The Crown 4 she is back in all her elegance and goodness in our lives. I tell my daughters about Diana and I am still shocked when I see what she had to endure and what she was not allowed to do. A photo of her running towards William with open arms, whom she hadn't seen for a week. Unheard of, according to The Crown, but exactly that made her the Queen of Hearts.
Her grave will be visited even more next year, due to the rekindled interest and because Diana would have turned sixty next year.
Lady Diana is buried on the Althorp estate, the estate of the Spencer family (her own family). The estate, which incidentally had the same landscape architect as Versailles, is open to the public for two months a year (in July and August). You cannot visit the grave, but you can look at the little island in the pond where she is buried.
How often do William and Harry visit their mother? Well, as far as we know, definitely during special occasions. For example, William and Kate went there a few days before their wedding. They were also there with their children on August 31, 2017, exactly twenty years after she died. Harry, Meghan, and Archie were there in 2019 on her death anniversary. On that day, Charles Spencer, Diana’s brother, always flies the Spencer flag at half-mast at Althorp.
Next year would be the year in which Diana would turn sixty. To celebrate that and to reflect on it, Harry and William have agreed to a statue that will be unveiled on July 1, 2021, her birthday, in the public part of Kensington Gardens.
You know what I hope? That William and Harry will stand there as brothers, side by side, and that all wrinkles will have been smoothed out. And that Elizabeth will pull aside her curtain, observe the scene (no idea if the statue will be in her line of sight, probably not, but hope is free) and then give a nod of approval.
