Kensington Gardens, once the private gardens of Kensington Palace, is one of the Royal Parks of London, lying immediately to the west of Hyde Park. Most of it is in the City of Westminster, but a small section to the west is in the Royal Borough of Kensington and Chelsea. It covers 275 acres.
The Gardens are generally regarded as being part of the neighbouring Hyde Park from which they were originally taken, but West Carriage Drive (The Ring) forms a theoretical boundary between the two. Kensington Gardens is fenced, more formal, and was long regarded as the smarter of the two. Together with Green Park and St. James's Park, these parks form an almost continuous "green lung" in the heart of London between Kensington and Westminster.
