It is shared between the City of Westminster and the Royal Borough of Kensington and Chelsea. The park covers an area of 111 hectares (275 acres). The open spaces of Kensington Gardens, Hyde Park, Green Park and St. James`s Park together form an almost continuous "green lung" in the heart of London between Kensington and Westminster.
