The statue was commissioned by William and Harry in 2017 to mark 20 years since their mother’s death and to “recognize her influence” around the world and will be placed in the garden of the London Palace.

Monday will mark the 23rd anniversary of the Princess of Wales’ death in a car accident in Paris. Kensington Palace said the installation of the sculpture was delayed by the coronavirus pandemic, but will be unveiled in Sunken Garden next year.

It was created by artist John Rank-Broadley. His portrait of the Queen appears on all British coins. More details on the design will be announced later, according to Kensington Palace.

When announcing the order, the princes said they hoped the sculpture would help everyone visiting Kensington Palace “think about its life and heritage.” “Our mother has influenced so many lives,” they said. The Princess of Wales died on 31 August 1997, when Prince William was 15 years old and Prince Harry was 12 years old.

Several memorials have been created in London in honor of Diana, including Diana Memorial Playground at Kensington Palace, Diana Memorial Fountain in Hyde Park and Diana Memorial Walk at St James’s Palace.

Another memorial, White Garden, was built at Kensington Palace three years ago.
