Home of the notorious May Fair and preferred residence of Royal ‘girlfriends’. Now, splendid residences and serious gossip. Once, a fair was held in May here. When it became too boisterous the land was sold for redevelopment and a new area developed. The Grosvenor family were key, now the Dukes of Westminster. Three splendid squares. Today, the home of great hotels and gourmet restaurants, great shopping and the most expensive square on the Monopoly board. Tickets and Times.
