The Garden at Buckingham Palace is a large private park attached to the London residence of the monarch. It is situated at the rear of Buckingham Palace, occupying a 42 acres site in the City of Westminster, and has two-and-a-half miles of gravel paths. Its area is bounded by Constitution Hill to the north, Hyde Park Corner to the west, Grosvenor Place to the south-west, and the Royal Mews, Queen's Gallery, and Buckingham Palace itself to the south and east.
The gardens are Grade II* listed on the Register of Historic Parks and Gardens. The planting is varied and exotic, with a mulberry tree dating back to the time of James I of England. The garden covers much of the area of the former Goring Great Garden, named after Lord Goring, occupant of one of the earliest grand houses on the site.
