Hill Street is a street in Mayfair, London, which runs south-west, then west, from Berkeley Square to Deanery Street, a short approach way from Park Lane. It was developed from farmland in the 18th century. Travelling one block to the east and south sees a fall of about three metres, whereas in the other direction the land rises gradually across six main blocks to beyond the north of Marble Arch (see Hyde Park). Hill Street's homes gained fashionable status from the outset: grand townhouses seeing use, at first, as seasonal lettings (rentals) and/or longer-term London homes of nobility — later, of other wealthy capitalists as much. Twenty-two, approximately half of its town houses, are listed. Along its course, only Audley Square House departs from townhouse-sized frontage, yet this shares in the street's predominant form of domestic architecture, Georgian neo-classical. Hill Street's public house is the oldest surviving one in Mayfair.
