The two years that Diana spent in apartment 60 at Coleherne Court were formative. She bought the apartment with money inherited from her great-grandmother. The price is £50,000 (US$67,000).

Diana moved to London when she was 18 years old and worked as a nanny and kindergarten. She began dating Prince Charles, heir to the British throne, in 1980 and got engaged a year later.

As her public profile grew, Coleherne Court was often besieged by photographers who wanted to capture photos of future princesses.​​​ After Diana was engaged to Prince Charles, her mother sold the apartment. Today it is still a private residence.

“Her troublesome marriage with Prince Charles and later relationship became the subject of media frenzy and intrusive reports, but she has earned a lasting reputation outside of her personal life for her extensive charity and humanitarian work.”

Famous people don’t have to be British to get the plaque. Foreigners who have lived in the UK, such as Mahatma Gandhi and Emile Zola, have also been recognized.

There are about 950 blue plaques in London alone.
