(CNN) – The London apartment where Diana Spencer lived before becoming Princess of Wales has been commemorated with an official blue plaque.
The plaque was placed in the Coleherne Court building on Old Brompton Street in Kensington on September 29 after a successful campaign led by the London Assembly.
“Diana had, and still has, a very special place in the hearts of Londoners and we are delighted to see her blue plaque formally placed as a monument to her work for others,” said Andrew Boff, President of the London Assembly, during the opening ceremony.
The plaque reads: “Lady Diana Spencer, later Princess of Wales, lived here 1979-1981”.

The two years Diana spent at Flat 60, Coleherne Court, were formative. He bought the apartment with money inherited from his great-grandmother. The price was £ 50,000 ($ 67,000).
Diana moved to London at 18 and worked as a babysitter and in a kindergarten. She began dating Prince Charles, heir to the British throne in 1980, and they got engaged a year later.
As her public profile grew, Coleherne Court was regularly besieged by photographers hoping to capture images of the future princess. After Diana got engaged to Prince Charles, her mother sold the apartment. It is still a private residence today.
“Her troubled marriage to Prince Charles and subsequent relationships were the subject of feverish and intrusive press coverage, but she earned a lasting reputation outside of her personal life for her extensive charitable and humanitarian work.”
These plaques are placed on buildings in England that are connected to important historical figures and are maintained by English Heritage. “Blue plaque detection” is a popular pastime for tourists and history buffs.
Notable figures do not need to be British to be honored with a plaque. Foreigners who lived in the UK, such as Mahatma Gandhi and Emile Zola, have also been recognized.
There are about 950 blue plates in London alone.
