In 1725, Mayfair became part of the new parish of St George Hanover Square, which stretched as far east as Bond Street and to Regent Street north of Conduit Street. It ran as far north as Oxford Street and south near to Piccadilly. The parish continued into Hyde Park to the west and extended southwest to St George's Hospital. Most of the area belonged to (and continues to be owned by) the Grosvenor family, though the freehold of some parts belongs to the Crown Estate.
