Diana, Princess of Wales – the late mother of Prince William and Prince Harry– died in a Paris car crash on August 31, 1997.
The comments featuring on the post pay tribute to Diana with one saying: “Sending you and your family a lot of love today”.
Another said: “Thinking of you all today. Our beautiful Princess, never forgotten, eternally loved and cherished.”
Many comments featured red love hearts and commended the act as a sign of “great respect”.
Others made reference to this heartbreaking day and the effect it will have on her family with one saying: “Sending prayers and peace for all the Spencer family today and of Course. Her beloved sons.”
The grounds of Althorp Park, Diana’s family home, where the gesture took place is the location of the late Princess’s final resting place.
Since the death of his father, John Spencer, in 1992 Charles has been the custodian of the estate.
Traditionally Prince Harry and Prince William mark the occasion of their mother’s death together, but a royal expert has spoken out as this will not occur this year for heartbreaking reasons.
Richard Fitzwilliams exclusively told Express.co.uk: “They always used to meet on this sad anniversary to relive memories of her.”
He said: “I think it likely they will be in touch but any contact between them will be private.”
The brothers unveiled a commemorative statue in the gardens of Kensington Palace in honour of their mother’s memory.
Earl Spencer was among those who were invited to the unveiling which took place on July 1 what would have been the princess’s 60th birthday.
Royal fans could mark the occasion today by visiting the statue of Princess Diana that was unveiled earlier this summer.
As this year marks 24 years since the fatal crash in Paris, special arrangements have been made to allow visitors to view the memorial near London’s Kensington Palace.
Historic Royal Palaces (HRP) said that for those who want to stop and take a moment, they would be allowed to see the statue from the Cradle Walk around the Sunken Garden where it stands from 3pm to 5pm.
