The Most Haunted House in London.
According to Charles Harper in his book Haunted Houses, published in 1913, 50 Berkeley Square has a long held reputation as being the "Most Haunted House in London."
The four-story brick town house was constructed in the late eighteenth/early nineteenth century. Until 1827 it was the home of British Prime Minister George Canning, commemorated by a plaque on the house today. The house was then bought by the Viscount Bearsted, who rented the property to one Mr Myers.[4] It was later bought by BP Since 1937 the building has been occupied by Maggs Bros, a firm of antiquarian book dealers. In 1998 the building was thought to be the oldest unaltered building in London.
Legend varies, but mostly states that the attic room of the house is haunted by a spirit of a young woman who committed suicide there.She purportedly threw herself from the top floor windows after being abused by her uncle; and is said to be capable of frightening people to death. The spirit is said to take the form of a brown mist; though sometimes it is reported as a white figure. A rarer version of the tale is that a young man was locked in the attic room, fed only through a hole in the door, until he eventually went mad and died. One story states that the attic room is haunted by the ghost of little girl that was killed by a sadistic servant in that room.
At least two deaths were attributed to the house in the Victorian Era after people spent the night in the room. The first ghostly happenings were reported by George Canning, who claimed to have heard strange noises and have experienced psychic phenomena whilst living there. After George Canning's residency in 1885, the house was bought by a Mr. Myers, who had recently been jilted by his fiancee. It was said that he would lock himself in the attic room and slowly went mad over the rest of his life. During his stay at the house, it fell into gross disrepair and it is during this time that its reputation began to build.
As a bet, in 1872, Lord Lyttleton stayed a night in the building's attic. He brought his shotgun with him, and during the night fired at an apparition. In the morning, he attempted to find the apparition, but could only find shotgun cartridges.[8] The next year the local council brought a summons to the house's owners for failure to pay taxes, but due to the house's reputation as haunted they were not prosecuted.[11] In 1879, The Mayfair Magazine reported that a maid who had stayed in the attic room had been found mad.[7] It was later reported that she died in an asylum the day after.[6] On the day she was found, a nobleman purportedly took up the challenge to spend a night in the room, and his was the first death recorded in the house. The coroner pronounced him dead of fright.
