Mayfair is an area of London, England, in the City of Westminster. It is in Central London and part of the West End. It is between Oxford Street, Regent Street, Piccadilly and Park Lane and one of the most expensive districts in the world. The area was originally part of the manor of Eia and remained largely rural until the early 18th century. It became well-known for the annual May Fair that took place from 1686 to 1764 in what is now Shepherd Market.
