Charles Spencer has performed a special gesture to honour Princess Diana's life on the anniversary of the royal's tragic death. On Tuesday, Charles made a social media post that sees him honouring his beloved late sister in a touching but solemn way.

Charles flies estate flag half-mast for Princess Diana

Charles took to Instagram to share an image of Althorp House, which is the family estate where he and Diana grew up. The flag is noticeably flying at half mast, which is a common show of respect to honour those who have lost their lives. While Charles did not caption the photo, royal fans understood the meaning behind it.

"Sad that Diana is not here to enjoy her gorgeous grandchildren," one commenter wrote. "Sending prayers and peace for all the Spencer family today," another said, also mentioning Diana's "beloved sons" Prince Harry and Prince William. Harry and William have of course paid tribute to Diana in their own way, making sure to uphold their late mother's legacy.

Althorp House also mentioned the special way Charles honoured Princess Diana's life shortly after her tragic passing. "There are 36 of these oaks, one for each year of her life," the estate wrote on Twitter, including a photo of the beautiful trees today. Back in June, Charles mentioned that he visits Diana's grave— which is located at the estate's Pleasure Gardens— "every landmark day," so it's likely he will be paying her burial place a visit today as well.
