As its Halloween why not visit 50 Berkeley Square, which is a reportedly a haunted townhouse on Berkeley Square in Mayfair, in Central London. In the late 19th Century, it became known as “The Most Haunted House in London”.

From 1770 to 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 Bearstead, who rented the property to one Mr Myers.

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.
