Mayfair is an affluent area in the West End of London towards the eastern edge of Hyde Park, in the City of Westminster, between Oxford Street, Regent Street, Piccadilly and Park Lane. It is 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.
