The unveiling, which comes more than three decades after the capsule was sealed, offers a poignant reminder of Diana's enduring legacy and the world she helped define.
The time capsule, originally intended to remain hidden for centuries, was unearthed earlier than planned due to the hospital's redevelopment project.
On Wednesday, Aug. 27, hospital officials opened that the box had been placed inside a wall in 1991, with the help of two children who won a competition on the beloved British children's TV show "Blue Peter." The contest asked young viewers to select items that best represented life in the 1990s.
Among the items Diana left, many of which were selected by children at the hospital, were a pocket TV, a Kylie Minogue CD, a collection of British coins, a snowflake hologram, a container with five tree seeds, and a solar-powered calculator, according to NBC News.
Diana, Princess of Wales, captivated the world with her compassion, style, and activism.
Born Diana Frances Spencer in 1961, she grew up in the British aristocracy and married King Charles, then Prince of Wales, in a globally televised ceremony in 1981.
The couple's marriage, which produced two sons -- William and Harry -- was closely followed by the public, as were their struggles and eventual divorce in 1996.
Throughout her life, Diana was celebrated for her charitable work, particularly her advocacy for AIDS patients, her campaign against landmines, and her support for children's health.
She served as president of Great Ormond Street Hospital for Children, among many other patronages, and was known for her hands-on approach and ability to connect with people from all walks of life.
Diana's life was cut tragically short at age 36, when she died in a car crash in Paris in 1997 while being pursued by paparazzi.
Her death sparked an unprecedented outpouring of grief around the world and left a lasting impact on the royal family and British society.
The opening of the time capsule, which had suffered some moisture damage but still preserved its contents, provides a tangible link to Diana's era and the values she championed.
The items inside, chosen to reflect the spirit of the 1990s, serve as a snapshot of a world on the cusp of the digital age.
