London’s Blue Plaques guide tourists through London’s diverse history by connecting famous Londoners of the past with the buildings in which they once lived in and worked. The aim of the program is to commemorate the unique relationship between individuals and places associated with them that are still standing today.
To some, the plaques are easy to miss. To others they are subtle and elegant. A London Blue Plaque is typically a ceramic disc 495mm (about 19 inches) in diameter and 50mm thick (2 inches). The exact look and feel has morphed over time, but most often they are circular and deep blue with white lettering.

Now run by English Heritage, the London Blue Plaques scheme was started in 1866 and is one of the oldest, continuous programs of its kind. Today, there are over 1,000 plaques across the capital city, on buildings humble and grand, to honor notable women and men through history.
Beyond tourism, the Blue Plaque program has been credited with saving buildings related to a famous inhabitant based on their cultural significance and their perceived value. Notable examples include the homes of Oscar Wilde in Chelsea and Vincent Van Gogh in Stockwell. Similarly, D.H. Lawrence’s house in Hampstead Heath was spared from the wrecking ball due to public awareness garnered from the Blue Plaque program.
Here are just a fraction of some of the history of London kept alive by their recognition through the Blue Plaque program.
On any list of the most famous addresses in London, 221B Baker Street would certainly rank quite high. Today, at the fictional headquarters of the creation Sir Arthur Conan Doyle, you will find the Sherlock Holmes Museum. If you gaze up to the second level of the building when entering the museum you will see a Blue Plaque that notes “Sherlock Holmes, Consulting Detective, 1881-1904” to denote the residence and offices of the celebrated detective from literary history.

The flat which Lady Diana Spencer, Princess of Wales received as a birthday gift for her 18th birthday is one of the most visited Blue Plaques of all. She lived at this location with three roommates until 1981 when she became engaged to Charles, Prince of Wales. The plaque was placed on this address of the famed Royal in 2021 and serves as a beacon to the streams of the late Diana’s many fans.
At 20 Maresfield Gardens you will find a building with a unique distinction. It is one of eighteen in the scheme where a location bears two separate and unique plaques. On this occasion it has the names of the former father and daughter occupants who contributed greatly to the field of psychology – Sigmund Freud and Anna Freud.
Meanwhile, on Brook Street in Mayfair, you will find neighboring homes that would have had two notable musical influencers living side-by-side had they been alive at the same time. On the classical music side, you would have found Baroque composer George Frideric Handel residing at 25 Brook Street. While on the rock and roll side, the guitar prodigy Jimi Hendrix made his home at 23 Brook Street. Today the property is home to the Handel Hendrix House museum where the two musicians were separated by merely a wall and 200 years.

The final address of Karl Marx in Chalk Farm received a Blue Plaque in 1937. It was repeatedly vandalized until it needed to be replaced. Sadly, the second plaque received the same treatment as its predecessor. When it came time to replace the disabled second plaque, the current building owner refused to have a third plaque installed. Meanwhile a blue plaque associated with an entirely different plaque program on the British coast in Ramsgate denoting the residence of Jenny Marx, “Socialist activist and eldest daughter of Karl Marx” remains mostly untouched.
In 2025, motion pictures will be represented with the addition of a Blue Plaque for Audrey Hepburn. Previously, cinema director Alfred Hitchcock’s home of 13-years was honored in 1999. Similarly, Charlie Chaplin’s home on Brixton Road not only noted its famous resident of years past – the plaque even details that Chaplin “lived here in Flat 15” in the early 1900s.
One of the most famous music albums ever recorded in London was undoubtedly The Beatles White Album. After the passing of John Lennon, Yoko Ono was present when a Blue Plaque was unveiled at the building where The Beatles made that infamous recording in 1968. A decade after The Beatles musical masterpiece was created at 34 Montagu Square, Bob Marley recorded his iconic album, Exodus, in Chelsea. Today there is a Blue Plaque that draws fans of reggae and the reggae and cultural icon himself.

Following in their footsteps, rock and roll legend and Queen frontman’s childhood home has a Blue Plaque. After Freddie Mercury’s death, his bandmate, Brian May, unveiled the plaque that still attracts fans eager to see where Fred Bulsara’s musical journey began and where he met future bandmates.
Literature is well represented by the Blue Plaque program. You will find Blue Plaques noting the long time residence of the novelist Charles Dickens, as well as the home of Virginia Woolf. Notably, on Woolf’s plaque she is titled not just as a “Novelist”, but also a “critic.”
For international fans of mystery, you can visit the residence of Ian Fleming, the “Creator of James Bond” in the City of Westminster. Or, if you’re a bit more daring, the home of the creator of some of the most respected sleuths and detectives in history by visiting the home of Agatha Christie in Kensington and Chelsea.

Ranked #52 on the BBC list of the 100 Greatest Britons in a UK-wide vote, famed healthcare worker and statistician Florence Nightingale is not overlooked by Blue Plaques. Credited as the founder of modern nursing, her longtime residence in Westminster is decorated by a marker.

Of course, one of the most famous Londoners, who is credited with staying in London while leading the entire nation through troubling times is honored with a Blue Plaque. The brick home where Winston Churchill died in 1965 has a standout blue plaque to mark his achievements so those called to visit the location or just passing by never forget.
Other notables include artist Vincent Van Gogh’s brief residence in Lambeth and where Mahatma Gandhi stayed while studying law at the Inner Temple and University College, London.
Blue Plaques are a city-wide scheme and therefore can be found to be broadly distributed throughout the greater London area. However, nearly a third of all the plaques can be found in the Central London borough of Westminster. Followed closely on the frequency list by the borough of Kensington and Chelsea and then by Camden.
For those seeking to explore London’s blue plaques, several methods are available. English Heritage provides a comprehensive “Find a Plaque” search tool on its official website, which allows users to search for plaques by name, borough or field of contribution – making it easy to explore specific areas of interest. You can also visit Open Plaques and Visit London to find out more.
