Kate Middleton left a touching handwritten note to honor those who have lost their lives to cancer while making an unannounced visit to a London art installation.

Princess Kate, 43, shared a montage of moments from her visit to the Ever After Garden — a seasonal outdoor space which benefits the Royal Marsden Cancer Charity — in a video posted on the Prince and Princess of Wales’ official Instagram on Saturday, Dec. 13.

“Thank you to all those who have contributed to the Ever After Garden, which raises vital funds for The Royal Marsden Cancer Charity. Every flower, every light, is a memory held together, an illumination of shared love, remembrance, and hope – C,” Kate wrote in the post’s caption.

In a moment near the end of the video, a small handwritten note can be seen nestled in the grass.

“In loving memory of all those who have lost their lives to cancer – C,” the note reads.

The garden, which showcases more than 30,000 glowing white roses, was created in partnership with designer Anya Hindmarch, writer Camilla Morton and the Royal Marsden Cancer Charity. The garden has raised more than $1.6 million for The Royal Marsden NHS Foundation Trust, a leading cancer hospital and research center, since it first opened in 2019, per the charity’s official website.

Kate and husband Prince William, 43, became Joint Patrons of the Royal Marsden NHS Foundation Trust in January. Both the Trust and the accompanying charity hold special significance for the couple, as Kate received her cancer treatment at the Royal Marsden Hospital in Chelsea following her cancer diagnosis.

“Her Royal Highness’ message over the last year has been one of resilience and hope, and her support for The Royal Marsden stems from a deep empathy for those facing similar challenges,” the Royal Marsden Cancer Charity wrote in their initial statement announcing the news early this year.

They noted that the patronage carries on a “proud tradition of the Royal Family’s support of both the hospital and the charity.”

“The Prince of Wales has held the role of President of The Royal Marsden since 2007; a position which was previously held by his mother, Diana, Princess of Wales,” they added.

Kate revealed her cancer diagnosis in a personal video message in March 2024. She started her cancer treatment in February 2024 — a little over a month after she had undergone major abdominal surgery.

She announced that she had completed chemotherapy in September 2024, and shared that she was officially in remission the following January.
