50 Berkeley Square

Number 50 Berkeley Square earned a reputation in the 19th century as the most haunted house in London. The attic room was said to drive occupants to madness or death — with a shapeless brown mass and a pale child among the recurring reports.

Today the building serves other uses, but researchers still trace the legend through newspapers and witness accounts. It remains a pin for London's darkest West End folklore even when the door is closed to casual callers.
