Princess Diana's brother Charles Spencer shares rare photo of her "hauntingly beautiful" grave

It has been eight years since Princess Diana's former chef spoke of his disgust at the "overgrown mess" of the late mother of two's grave site within the Althorp estate in Northamptonshire.

But now the island where the "People's Princess" is buried has received a multi-million dollar facelift, as part of the Spencer family estate gardens' first major revamp in 350 years - and it is looking hauntingly beautiful.

Diana's final resting place - which is at her childhood home - has gone from being shrouded in overgrown greenery and moss to being clean and surrounded by immaculate gardens and a crystal clear lake thanks to the 18-month-long restoration project.

And much to the delight of royal fans, Diana's brother Earl Charles Spencer has shared a rare photo of the island.

Taking to social media, the 58-year-old posted two images of his property, one of the exterior drenched in an eerie mist and another of the foggy lake where Princess Diana has been buried.

A plinth with an ern on top can be faintly made out on the island, as part of Diana's memorial.

Charles captioned the post: "Beautifully foggy morning today."

When members of the public visit Althorp, they are unable to access the island to pay their respects.

It has been 25 years since Princess Diana died at the age of 36, when the car she was travelling in crashed in a Paris tunnel on August 31, 1997.
