50 Berkeley Square
A Mayfair townhouse whose attic room was said to drive Victorian visitors mad, now quietly empty behind a blue plaque
Photo: Wikipedia
50 Berkeley Square has been called the most haunted house in London since the 1870s, which makes it one of the oldest "most haunted" claims in the country. It is a handsome but unremarkable Georgian townhouse on the west side of Berkeley Square in Mayfair, a Grade II listed building with a blue plaque to the Prime Minister George Canning by the door, and for most of the twentieth century it was the home of Maggs Bros, the antiquarian booksellers.
The legend concerns the attic room. Depending on who is telling it, the room is haunted by a young woman who threw herself from the window to escape an abusive uncle, by a young man locked in and fed through a hole in the door until he lost his mind, or by a shapeless brown mist known simply as the Nameless Thing. Victorian magazines reported a maid driven mad, a nobleman who fired a shotgun at something in the night, and two sailors who broke in for shelter and fled in terror. Later writers, including one who interviewed the family living there in 1912, concluded there was nothing in it at all.
This guide separates the history from the legend, explains what you can actually see at 50 Berkeley Square today, and suggests where to stay in Mayfair and the West End.
Hauntings are told as reported — by owners, guests, guides and investigators — never as fact. The history underneath is often real, and sometimes tragic; we treat it with respect. Background from Wikipedia and the sources listed below.
The history behind the hauntings
Berkeley Square was laid out in the mid-eighteenth century and its townhouses were built for the fashionable and the well-connected. Number 50 was the London home of George Canning, who was Prime Minister briefly in 1827; the Greater London Council put up his blue plaque on the house in 1979. Nothing in Canning's time suggests anything strange about the building.
The house's reputation begins with a later tenant, Thomas Myers, who occupied it from 1859 until his death in November 1874. Myers is said to have been jilted by his fiancée and to have retreated into the house, sleeping by day, wandering the rooms by night and letting the building decay around him. To the neighbours, a dark, neglected house in a smart square with a recluse inside it looked exactly like a haunted house, and by the time Myers died the stories were already circulating. In 1879, an article in Mayfair magazine claimed that a maid who had been put to sleep in the attic room had been found raving and had died in an asylum the next day.
The stories gathered momentum through the late nineteenth century and were collected by the writers of the Edwardian ghost boom. Charles G. Harper illustrated the house in Haunted Houses in 1907, and Jessie Adelaide Middleton devoted a chapter to it in The Grey Ghost Book in 1912, for which she interviewed the then tenant, the Countess of Selkirk. Maggs Bros bought the building in the late 1930s and traded there until 2015, moving to Curzon Street the following year. The house has stood empty since February 2020.
The ghosts of 50 Berkeley Square
4 reported apparitions, as the stories are told.
👻 The Nameless Thing of the attic room
The top-floor bedroom
Most versions of the legend agree that whatever haunts 50 Berkeley Square lives in the attic room, but they disagree about what it is. The commonest tale is of a young woman who threw herself from the top-floor window to escape her uncle, and whose spirit appears as a brown mist or a white figure capable of frightening people to death. Others describe a young man locked in the room and fed through a hole in the door until he went mad and died, or a child murdered there by a servant. The vaguest and most unsettling version simply calls it the Nameless Thing, a shapeless presence that fills the room with terror.
👻 Sir Robert Warboys
The attic room
Sir Robert Warboys is the legend's archetypal sceptic. A nobleman who scoffed at ghosts, he is said to have accepted a dare from friends to spend a night alone in the attic. According to the tale he saw an apparition in the form of a brown mist, felt a terror he could not explain, and fired his pistol at it to no effect. Accounts of what his friends found in the morning differ, and none of them ends well for Sir Robert. No record of a Sir Robert Warboys has ever been found, and even sympathetic writers treat him as folklore rather than history.
👻 Lord Lyttelton
The attic room
The earliest definite account of a night in the room comes from George, Baron Lyttelton, who is said to have slept in the attic in 1872 after a friend dared him to. He took a shotgun with him and, according to the story, fired at a shape that came at him in the darkness; in the morning there was nothing to show for it. Lyttelton died in 1876 after throwing himself down the stairs of his London home, and later writers could not resist suggesting that he had never recovered from what he saw. The link is speculation, but the Lyttelton story is the one most often cited as evidence.
👻 The two sailors
The attic room and the front railings
The most vivid tale is of two sailors from HMS Penelope, named as Robert Martin and Edward Blunden, who came up from Portsmouth, ran out of money and broke into the empty house to sleep. They chose the attic room. During the night Blunden woke to see something grey crawling across the floorboards towards them. Martin fled and fetched a policeman; when they returned, Blunden was found dead, impaled on the railings below the window. Sources cannot agree on the date, placing it variously in 1843, 1887 and even 1943, which tells you a good deal about how the story has travelled.
Sightings, investigations and published accounts
Almost everything reported at 50 Berkeley Square comes from the nineteenth century, and much of it from print rather than from named witnesses. The 1879 Mayfair magazine piece about the maid is the earliest published account, and the Lyttelton night of 1872 is the earliest with a named participant. Victorian newspapers and society magazines repeated and improved on the stories, and by the 1880s the house was routinely described as the most haunted in London.
The sceptical case was made early and has never really been answered. When Jessie Adelaide Middleton researched The Grey Ghost Book in 1912 she interviewed the Countess of Selkirk, who was living in the house, and found no trace of anything unusual. "So the mystery of Berkeley Square resolves itself into nothingness," she wrote at the end of her chapter. Maggs Bros, who occupied the building from the late 1930s until 2015, reported no phenomena in nearly eighty years, though staff cheerfully kept the legend alive, and the firm still publishes a light-hearted piece about the basement on its website. Modern investigators generally conclude that the reputation grew out of Thomas Myers's eccentric, shuttered years and was then embroidered by writers who never set foot inside.
That has not stopped the London Dungeon from building a show around it. The Nameless Thing has proved more durable than any named ghost, precisely because nobody can say what it is.

Visiting 50 Berkeley Square
50 Berkeley Square is private property and has never been open to the public, so a visit means standing on the pavement. It is easy to find: the west side of Berkeley Square in Mayfair, London W1J, a few minutes' walk from Green Park and Bond Street tube stations. From the square you can see the plain brick front, the tall sash windows and the blue plaque to George Canning, and you can look up at the attic window and decide for yourself. The building has stood empty since February 2020, and a private members' club group has put forward proposals to refurbish numbers 49 and 50 as a wellness and spa destination, so its appearance may change.
The square itself, with its enormous plane trees, is a pleasant place to sit, and the surrounding streets are full of galleries, pubs and restaurants. The London Dungeon on the South Bank has a 50 Berkeley Square attraction if you want the story with special effects. For a bed, Mayfair has some of London's grandest hotels, and there is a wider choice within a short walk around Piccadilly, Soho and Marylebone.
