More formal than neighboring Hyde Park, Kensington Gardens was first laid out as palace grounds. The paved Italian garden at the top of the Long Water, the Fountains, is a reminder of this, though of course Kensington Palace itself is the main clue to the gardens' royal status, with its early-19th-century Sunken Garden north of the palace complex, complete with a living tunnel of lime trees (i.e., linden trees) and golden laburnum. Several landmarks are worth looking out for: George Frampton's 1912 Peter Pan is a bronze of the boy who lived on an island in the Serpentine and never grew up and whose creator, J. M. Barrie, lived at 100 Bayswater Road, not 500 yards from here. Southwest of Peter at the intersection of several paths is George Frederick Watts's 1904 bronze of a muscle-bound horse and rider, entitled Physical Energy. The Round Pond acts as a magnet for model-boat enthusiasts and duck feeders. By the children's playground on the north of the Broad Walk toward Black Lion Gate is the remains of a tree carved with scores of tiny woodland creatures, Ivor Innes's Elfin Oak. The Princess Diana Memorial Playground is a fabulous enclosed space, which besides the usual play apparatus has specially designed structures and areas on the theme of Barrie's Neverland. Hook's ship, crocodiles, "jungles" of foliage, and islands of sand provide a fantasy land for kids. Tube: Lancaster Gate or Queensway.
