Mayfair is a small neighbourhood in London with 18th century houses and luxurious hotels, the most expensive boutiques and clubs. Up until the 18th century the Shepherds Market was found here, and annual fairs took place in May, hence the name of the area. The oldest auction firm Sotheby's is headquartered here.
Mayfair has not always been all about luxury and refined shopping. Where the Marble Arch stands now, erected in the 1828, there used to be a public execution place (from 1388 till 1783), complete with the Tyburn Tree, a triangular gallows where 24 people could be hanged simultaneously.
