Laid out during the reign of Edward VII, re-creating the formal gardens that existed at Kensington Palace in the 17th century.
It is terraced with paving and flower beds, surrounding an ornamental pond with fountains.
Today, the garden continues the tradition of rotational flower displays in the spring and summer.  Vibrant colours and exotic planting are on display from April to October when the garden is looking its best.  In the spring, tulips, wallflowers and pansies bloom, while in the summer months, geraniums, cannas, begonias and much more provide the colour.
The Cradle Walk, known as 'The Bowery' was created in 1908 by the historian Ernest Law.  Planted with red-twigged lime (Tilia platyphyllos 'Rubra'), took visitors around the Sunken Garden.  It flourished until 1987 when it was cut back after the Great Storm and cut down in 1988.  It has now been completely refurbished, recreating the walkway, returning the garden to its original glory.
