The grounds as they appear today were laid out in grand style in the late 17th century. There are no authentic remains of Henry VIII's gardens, merely a small knot garden, planted in 1924, which hints at the gardens' 16th-century appearance. Today, the dominating feature of the grounds is the great landscaping scheme constructed for Sir Christopher Wren's intended new palace. From a water-bounded semicircular parterre, the length of the east front, three avenues radiate in a crow's foot pattern. The central avenue, containing not a walk or a drive, but the great canal known as the Long Water, was excavated during the reign of Charles II, in 1662. The design, radical at the time, is another immediately recognizable influence from Versailles, and was indeed laid out by pupils of André Le Nôtre, Louis XIV's landscape gardener.
